Anyone ridden the Mojo Nicolai yet?

Speeder, that particular bike isn't (the article isn't quite accurate to my annoyance) the production numbers are as per the drawing earlier in the thread, I posted them. That bike is custom geo for the lad, and not the same. Article is a bit of a hybrid about that bike and how it came to be and a separate process for pulling together a smaller GeoMetron. Seems to have been lost in translation.. the sentiment is right though. Wanted a proper bike for kids and smaller peeps.

Thanks for the info Chainline

Even if it's not the "standard option" It does go to show what can be done on the custom program. I'm just shocked that a 12y/o needs a bike that's more bling than the bike I've just built that's the most expensive bike I've ever put together. Still, competitive dad is competitive dad.

Welcome sofaking

Speeder, yep, but if you have the money and your kids love it, fair play, beats the sofa

Amen to that Chainline 😀 - I'm sure I'd be very tempted to bling up the kids bikes and go riding loads if I won the lottery. He's one lucky kid.

Nicolai have been doing this for a long time. My youngest daughters bike was originally commissioned by Simons_Nicolai-uk back in the late 2000s I am told for his partner, its a Nonius design, which at the time could be made smaller than a Helius, with a 12.5" ST. It has similar geo to the bike shown in the article, tho built lighter in this version with a bunch of my old 26" parts and a custom Mojo shock, so is pretty conventional in proportions. It's a 130mm/130mm with a 68HA in this form. She's been on this since age 10 and about 4'7".

Orange did the same with the Diva, a long and std version which eldest daughter has been riding. That bike was actually the same as a 14" five. The addition of a 35mm stem, angleset, 100mm dropper and 155mm Canfield cranks brought it easily within the bounds of a 4'9" 11 yr old. This one is 140mm/140mm and has a standover of just under 680mm.

So it's been wholly possible for a long time if you were committed to it for your kids, either through a custom route or carefully selecting components.

What I wanted to do was take the forgiveness and confidence a GeoMetron provides with the same geo and apply that to kids bikes and smaller people, make it really accessible, drive the standover below that of even a 26" Diva (the new XS GeoMetron is 660mm) but make the reach and HA, WB etc forward thinking. So they don't have to think about 'adapting' or riding differently, it's what they know from the start. Both of my kids have been riding long, slack bikes for their size since 6 (When they had 14" OnOne Inbreds with adapted SID's, 24" wheels, 30mm stems and modified cranks at 145mm, the Inbred has a super low standover) I've compensated with the setup so long is normal to them. Neither of them are super great or super fast but they enjoy it, are confident and happy to ride lots of stuff, do some jumps and drops, ride down steps etc. so it's been a win from my perspective and keeps me closer to my girls with a shared hobby.

Can't wait for the GroMetron to arrive..

if anyone wants ideas for their kids bikes or help and what parts can be used to good effect now low cost 26" parts just ask or msg me, here's the bikes I built for mine. 14" Five or Diva is ideal from 10-11yrs (or earlier if they are taller, but hard to find used. However Orange will refurb it for £200 to look like new.

There are some parts worth investing in like the cranks and suspension. Deore 11spd or SLX is now cost effective..

I had a test ride day on Friday at BPW . Top service from Toby . A very frienndly and knowledgeable guy with a real passion for helping you get the most out of the bikes.
I test rode the G13 and the G16. Both bikes are truly amazing to ride and very capable machines both up and down the hills. The G16 is a lot more bike than the G13 so if anyone is in two minds about these bikes I recommend you swing a leg over one or both. you might be pleasantly surprised

What are you buying, sk?

although the G13 felt a very capable bike and would have probably been enough bike for me, the fact that the G16 went up hill so well and was even better on the descents made it an easy decision.
if I only had one bike to ride I would have gone for the 13, but I am lucky enough to have a couple of other bikes to ride too

Sofaking, enjoy 🙂 Don't forget you can always try a few configurations on the G16. I look forward to some wider feedback from you 🙂

Chainline. cant wait to get it now.i like the fact the new 16 can run 29er wheels although not sure how yet

Hi everyone,just buyed a Nicolai G16 with Fox Float X2 shox
Please is the someone out there that can give me a good starting set up for the X2?
How many clicks and eventually how many spacers?
Excuse my bad english

Sofaking. You can either get a modded fork supplied with 27.5 180mm uppers and 29 lowers which can run both wheels (at 180mm, 27.5 or 170mm, 29) or just get spare lowers to be able to switch.

At the rear, just swop out the wheel! Either travel works.

Chainline the g16 that fits 29 wheels is this the current version that mojo are selling?

I assume you could just fit a 29 fork as standard from the out set.

Yep. but there are few people use it

blakec yes you can do that with the 160mm 29er fork or use the 27.5 180mm uppers and 29 lowers as mention to go a little longer.

Finally building mine up with the 29 front wheel this weekend, although in the 40's at the moment.

Chainline. Great thanks for the response going to see mojo on Monday to have a chat

Thanks

Current project, 2017, not finished yet. 27.5/29 setup. Will be using both the 40 and a 36 I think.
Need to fit the crank, tune the fork for 175mm travel and balance the stantion position with offset bushes to get the BB to 338mm.

All the other set up is my standard apart from the bar is a little high at present (will change when I've made the adjustments)

Rider height 178cm

BarEnd to BB - 915mm
Centre of seatpost/saddle to centre of bar 680mm
Stem 30mm
Bar 800mm with ESIs
Bar height 1110mm (Target back to 1070mm)
BB - currently 343mm, planned 338mm
Rear travel 155mm/175mm Front travel 175mm (29 wheel)
Magic Mary in the front with 3mm clearance to arch
Rear wheel Stans Bravo 32h built onto Hope Boost hub with CX-rays
Front Wheel Enve AM built onto Hope hub, 20mm axle, CX-rays
HA 61.3deg
SA 76.5 deg

That CNC yoke is a piece of art! I love Nicolai and I've followed this thread from the start. I've always loved the welds and precision engineered look of them. Not sure it suits my current riding, but would love one once I've moved somewhere hillier.

Currently trying to get my dad on one of these and off his ancient Trek.
The G13 appears to fit the bill. Just need to organize a test ride day. He's in Zurich so plenty mountainous over there.

Hey Chainline,
another lovely build. Thanks for posting all the pics.
That rear clearance is excellent.
Might even get a 2.5 Maxxis in there comfortably if needed for Alpine.

Hey comodiver,
I've ben on the Geometron from it's early days

Settings would be somewhat dependent on weight (pressure). I am 80kg and use the longer chainstays to give 175 travel with a 222 x 70 Shock.
all settings clicks out from full on:
222 x 70 Shock
6 spacers
HSC 22 /
LSC 20 I started at 10 (And Mojo said go even to to 8 LSC or 6 if it feels soggy, it doesn't)
HSR 19 (Mojo ADVISE less LSR (faster return) say +2 for high speed, that would be 21 clicks out)
LSR 9 (in soft ground, can use a bit more damping, so - 2 = 7 clicks out)

on the 215 shock I was on: HSC22 LSC 10 out, HSR17 LSR 3
Hope it helps
neil

the new X2 has plastic spacers (or post recallshocks) so Mudfish essentially has max spacers allowed.

the new X2 has plastic spacers (or post recallshocks) so Mudfish essentially has max spacers allowed.

There must have been an intermediate version of the X2 - mine was pre-recall but had plastic spacers (and no limit ring). I've not opened it up since it had the new can on it.

They did release the plastic spacers pre-recall with no limit ring but still a max number specified which gave a slightly larger residual volume than maxing out with the foam ones I think.

Chainline, any idea what the clearance is like on the rear with a 29er wheel in there? If it's the same rear end it looks like it may be a bit tight?

I'll take a pic this morning.

I'm just awaiting a set of Boost Bravo's so I can set it up properly for 29 and then do some proper testing and demoing with it, fit a long travel 29 36 too.

The 'special' 150mm G13's have generated a lot of interest and there is a desire to offer the 16 with better knowledge of how best to set it up as a 29er as well as 27.5/29 (That is already pretty nailed) so customers can be well informed.

The plan is to run 155mm rear and 160mm-170mm front with either a standard or ebike fork depending on preference. (Standard can use 15 or 20mm axle) as well as boost version. I think e-bike is only boost but has stronger stantions and crown but is of course slightly heavier as a result.

Looks ace,CL.

Any reason for the reversed shock?

fiddling with shock bushes and clearance. other way around now. fewer bushes, smaller shock.

Right, makes sense.

Meant to drop you an email, ran a shockwiz on my fork last night, other than a couple of clicks of high speed, it was very impressed with the fork tune you suggested. All pretty much spot on. Just me to blame now 🙂

Good news HonourableGeorge 😀

Not even remotely tight.

Just going to check the BB heights with 36's fitted. Need to lift them to 160mm first! It's 350mm with the rear shocks set correctly. I think it will sit at around 338mm with the 216mm shock in but the chip at 222mm.

Horses for courses really on BB height/drop. fine tuning with bushes. I'll measure up the angles too with the angle finder. Not an ideal wheel combo to use for me but until the fancy wheels arrive I'm sure they will be fine. I can swop between the 27.5 and 29 rear very quickly between runs. and adjust the BB.

Hi all, just thought I would report the weight of my 2017 G16. All built, ready to ride, with lots of carbon bits, it weighs about 31.75 pounds, or 14.4 kilos. Deduct a few grams for a light coating of Arizona dust. 🙂

So this is now a 29 for testing, there has ben a lot of interest in the 29 version with longer travel so I wanted to do some more detailed testing to determine the best setup with the G16 rather than the G13 as a custom, Chris is doing the same and I think Toby too.

Just waiting for the @hopetech oval now for the @hopetech cranks then I can go riding. @mojosuspension G16 running 29 wheels.
155mm rear currently (I will use the 175mm to but not until I want the higher BB and we have sorted the longer travel 29er fork.
160mm front ebike 36, which is heavier than std at 2.2kg but stiffer.
BB set at 340mm (plan testing between 340,345 & 350mm as I have a theory!)
HA comes out at 60.5 and SA 76.2 but saddle set to give 77deg. Measured on the trusty digipas anglefinder and a straight edge.
First runs will be with the Hopetech enduro wheels until the @stansnotubes Bravo wheels in boost arrive to lighten things up.
A @vittoriauk_tyres Morso graphene tech rear ready to go on.
My usual @hopetech brakes, @envecomposites DH bars, 30mm #syntace stem, ESI grips and @selle_italia slr kit carbonio saddle.

All built, ready to ride, with lots of carbon bits, it weighs about 31.75 pounds, or 14.4 kilos

What wheels and tyres are you using?

That looks great Phil, the raw frames are nice. My black one is a bit brown after 18 months, the MucOff wasn't really lifting it over the winter. My G13 is in Low with standard bushings and a -2 headset, I like it that but I would like to try a 29er with 36s and an X2.

Chainline, is that the longer swing arm to allow for the 29er rear?
I'm just about to put a 29er wheel up front on my G16. But this is for a different approach. The plan is to use the G16 frame for mountain mayhem. fox 34 29er up front with stans crest rim, with fox rp23, fixed seat post. all to try and get the weight down. I have a sneaking suspicion, I will want the 29er lowers on the 180 36 and the x2 back on after the race for trai riding.

Beast of a bike!

How do these bikes feel with the 60 - 61 HA?

I seem to remember reading (possibly buried within this thread somewhere) that the steering slows as the HA slackens, but then around 63 the wheel flop counteracts that to start quickening the steering again.

Counterintuitive but it kinda makes sense.
I hope so at least, as my slacktastic new hardtail should arrive within the next few days!

My black one is a bit brown after 18 months, the MucOff wasn't really lifting it over the winter

Spray WD40 or GT85 on a rag and wipe it over to clean it up.

Paul J. No longer swingarm required on the 2017 model due to the revised yoke and wider BB. Lots of clearance with either 445mm or 450mm chainstay length.

Your description (apart from the 29 front) is where we will pitch the kids bike with 34's and DPS. You should get that to around 28lbs with crsts and 1x gearing.

Bedmaker 61 feels fine and yes the steering speeds up again, not everyone likes the feel just like not everyone likes it steeper 😉

@chainline that looks rad!

I'm thinking of getting an angleset for my G13 and wondered what your thoughts are on how slack to go? I'm having to run it in the high position due to pedal strikes (I live in the lakes so lots of sniper rocks!) but preferred the handling in the low setting.

Whats this 150mm G13 you've mentioned too?

If it's a ZS44/56 head tube (I can't find the info on the Geometron website) then I'm just about to take the Cane Creek Angleset out of one of my bikes, which can give you -0.5/1/1.5 options with swappable cups, so that'll be looking for a good home!

@chiefgrooveguru yeh that's the fitment if I remember right. How much you looking for?

£60 posted ok?

It's OK with me if it's not OK with RR 🙂

Have there been any definitive views as to the 2017 G16 pared with 29 front 27.5 rear yet?
Seems as though it could be the best of both worlds! ( if that is ever possible)
Thanks in advance

Catvet..hehe. I know you have mailed me but I can tell you that you would have to prize the 29/27.5 GeoMetron out of Chris's cold dead hands..

Having spent the weekend on the 29 version, I liked it, I got used to it, but it was the front that stood out as a great balance at 60.5 HA. I had to work to steer the rear more, which I am not used to now and is not my preference.

It was both fast and handled nicely (once I was used to the different feeling) even on the tight tracks of Staunton.

I think the 29 would suit a bigger stronger guy. I'll be testing the 27.5 rear at the weekend bakc to back on the same tracks with the 29.

My 29er'd Longest and CP's XXL complete with lead! Rather him than me...fork as mentioned is the ebike fork.

I'm having to run it in the high position due to pedal strikes (I live in the lakes so lots of sniper rocks!

even on the tight tracks of Staunton.

Been looking at replacing my Reign for a little while and currently the starling, geomteron & slash are on the list (wasn't that impressed with the enduro, although it was only the RS equipped on).
My first impression of the geometron was at cannock, which is the least ideal place to demo one! But definately buy into the setting the bike up properly, although am a little concerned about the shear length of the bikes and the slack head angles (I dont ride over the front, more
middle/middleback. Noticed a commented from JimBuchannen about the length/slackness of his starling and seeing him riding it at eastridge, that front wheel is a long way out the front!

After the Mega will have to contact Mojo and see if I can demo a bike at staunton.

Noticed a commented from JimBuchannen about the length/slackness of his Starling

Is CP running no wiper seals in his forks?

The Starling has short chainstays and a not very steep seat angle, add to that a not short enough stem and you have problems.

Jim's Starling has 455mm chainstays and the 75 deg seat angle has no bearing on the handling except when seated. And the stem is 40mm long...

Now that CP has come around to 29er, how long before he realises he's wrong on B+? 🙂

Hurry up...get a wider yoke organised!

Don't hold your breath/not a hope in hell on that one bedmaker. He was straight off the 29 full version, didn't ride it for long at all. The front is a different matter.
Like me it's a good bike if you like that feeling, but he doesn't like the way it steers.
I think it steers much better with these angles, similarly a G13 with -2, than at mid 64's. The flop, offset and trail just do seem a nice balance.

Much as I adore the 40's the offset of 51 at such a slack HA made the steering 'almost' too responsive. I became used to it and stability didn't suffer but it was more sensitive than in this set up. That's not a surprise but I did like the feeling on this one.

Rick, now that is some eagle eyes!! He isn't...they are an experimental special. And very amazing they feel too. If ugly as sin presently. I shall be trying the same mod shortly I think. So little stiction.amazing when compared back to back with one with wiper seals. Of course it still has to be sealed!
Have to see how the 27.5 rear fares.

I do t advocate by one doing it but I suspect a b+ tyre would fit in the rear there is that much room even with a 29er. Something like.2.8, possibly a 3.0 but they are horrible things. I preferred 29+. B+ seems so sensitive to tyre pressure and of course the punctures and the weight in the wrong place...

Chainline - what difference does the -2 make on the stack height? I assume lower but is the difference diddlysquat. And are your G13 forks still set at 140mm or do you account for the lower stack by jacking them up to 150mm?

I love the way my G13 rides and I seem to be continually setting faster times on it but also curious about the slacker head angle. That said I do like the fact that it feels like I have to muscle it into corners at higher speeds as, to me, it adds to the feeling of stability which in turn gives me confidence. I'm also 6ft 4 and 100kg so the effort required for me to tip the bike in is probably far less noticeable.

I am also still coil curious for the rear. Having to pump the shock to around 300psi to get the required sag gives me a nagging feeling that I'm missing out on some of the benefits as a result of running it at the extreme of its operating range.

What are the options for running 29" wheels on the geometron? Is it just the G13 or could the G16 run 29" wheels front and rear?

Ideally I'd like a long travel 29er geometron.

Ganic... see pictures and write up. That is a G16 29er GeoMeteon I was/am talking about.

Gotama, that was one of my points and heavier rider may prefer that feeling, likewise an aggressive one.
If you use a superstar or works the change in stack height depends on if you had the steerer slammed or not.
The offset is st the top and the bb change is minimal so if you have 10-15mm spacers, no change. It can also be reset with bar/negative rise stem e.g Syntace -6deg 30mm.

Ok, thanks, food for thought.

I run 15mm of spacers and a 35mm rise bar so plenty of scope to mess around there.

Yep. Sounds like a no lose eat apart from the cost of the headset.

Just ordered myself a G13. And now begins a 6 week wait!

BIGMAN...and a -2 headset 😀

Chainline, is it possible to test the 29 G16 set up anywhere?

It's abit of a departure from my 2017 Enduro 29 in terms of HA, reach and chainstay length.

Toby has a setup, Chris does and I do. Essentially yes. Mojo would set a demo bike up for you in the preferred size.

You could try mine depending on what size you are and where you are?

I'd recommend you test a 29/27.5 too since it is so easy to swop between them.

Jim's Starling has 455mm chainstays and the 75 deg seat angle has no bearing on the handling except when seated. And the stem is 40mm long...

@Chainline - I live in Kent so not sure the - 2 degree is needed. Would it add performance values even on flatter trails?

BIGMAN, yes. in my opinion of course. just because it's flatter doesn't mean you aren't travelling, it's more related to a combination of turn in and grip. You should find you can weight the front more into a corner and that it will hold a carve better, it will also speed up turn in. What offset fork are you running as that does have a bearing.

"Jim's Starling has 455mm chainstays and the 75 deg seat angle has no bearing on the handling except when seated. And the stem is 40mm long..."

That's not quite true as it has a bearing on the overall geometry. with a steeper ST, the whole front of the bike is pushed forward relative to a given ETT and CS length, making it longer and changing the weight distribution, although I agree mostly in seated riding.

It is compensated for here by a longer chainstay, but the Geo is straight of a Mojo apart from the SA, so very flattering...I think it might not take on the steepest of slopes with that HA and SA as well without more rider adjustment on the saddle. I find the G13 as standard more difficult (tho not difficult) than the G16 on very steep climbs even though it's only a degree or so slacker in the SA.

Chainline: In reality then how much difference is there between the G13 and the newer G16? Im looking at XL G13 with a customization off fitting in an X2 shock, and a 62 degree head tube in the high setting. Then I wonder is that just the G16 with 29er wheels fitted?

Paul j That would indeed be a G16 with 29 wheels fitted when in the low setting. Although they may tweak the linkage ratio if you want a 135mm rear end if you just allow the X2 you get approx 150mm.

The G16, to get an ideal BB (although that is a matter of personal taste), ends up a little slacker at around 61deg but at that point is basically a slacker G13 with 150mm travel and the option to make the most amazing 27.5/29 hybrid 😉

IF you were still minded to go custom to eliminate the slight compromise on the SA (I can confirm that it is un noticeable on the trail (and at 76.5 is still steep compared to most other bikes) and climbs brilliantly,
I'd suggest a G16 but 'reset' to work perfectly with your preferred wheel size without any shock offset adjustments (it is however only one offset bush which allows massive flexibility in the bike with little or no compromise) what you lose is the ability to use 170mm with a 29 rear wheel as it makes the BB too high
If your wheelsize of preference is 29 then it's just a matter of specifying that the BB is 335 - 340mm with the 740mm dia rear wheel.

I'd suggest you get a demo on a 29er'd Mojo G16 XL and a -2 headset G13 you'll know for certain then.
If you did do the G13 custom, I'd adjust the BB and the SA too to 335mm and 77.5deg as well as the HA to 62.

Don't forget the G16 has an 83mm BB if you were thinking of moving cranks.

Legend you are chain line.

Is there much difference in weight between the two frames, it will be used for a lot of alpine singletrack, with a fair bit of pedaling, and trail riding.
occasionally used for an uplift etc.

As you say i think testing the G13 with a -2 against the 29er xl geo.

much appreciated chainline.

Possible to get the longer swing arm on my 2016 mojo G16, and fitting 29er front and back?

hmmm, not sure anyone has tried to fit a 29 in the rear of the 2016. Its great with a 160mm 29er front and longer swingarm with 27.5 rear. Angles and bb are spot on with no adjustment.

The new swingarm yoke is what allowed the change to use a 29 wheel it has more clearance. There isn't any reason to not be able to use the new swingarm I don't think but its £400. Would need to check as it replaces the rear bush with a bearing so its possible it may need seatstays too but could still be cheaper than a new frame.
You would have to ask CP if its actually possible, or I can if you want.

I would highly recommend, if you're current frame is the right size, trying it with a 160mm 29 front fork.

Thats easy to facilitate. Where are you. If it was a preferred option it is just a case of swopping fork lowers.

Do you have an xl already.

Sorry there are so many possibilities...

I have the longest, G16. I need to the 180 36 and x2. Serviced so may drop it in, see if I can ride the G13 with angle set and then have a chat.

Chainline, what rear shock length are you recommending with the 29r 27.5 hybrid?

either works well enzocycling. 216x63 or the 222x70 on a 2017 model. Depends on your preference.

I personally like the 170mm 222 just because it gives my knees less grief in the really rough stuff I sometimes ride. The 216 155mm feels livelier if you want it to as you can deliver a smaller air chamber.

They both work perfectly with the hybrid in terms of geo. It's only when you want to run the 29 rear wheel I'd recommend the 216mm only due to BB height.

That's not quite true as it has a bearing on the overall geometry. with a steeper ST, the whole front of the bike is pushed forward relative to a given ETT and CS length, making it longer and changing the weight distribution,

I'm not convinced that's really the case. When you're standing the position of the front of the bike is determined by the fork length and offset, the head angle, the head tube length and the reach, with the rear of the bike determined by the chainstay length, and the stack and BB drop dealing with the vertical aspects.

I don't think I've ever noticed the non-seated handling (i.e. downhill) being at all affected by the saddle position on the rails (I believe there's about 2 degrees of effective seat tube angle available) but it does have a big effect on seated pedalling, both on the flat and when climbing.

I may have missed this earlier in the thread but whats the weight of the g16/geometron frame with the x2 shock?

Nicolai website states 3500g for frame without shock, so guessing about 4000g for frame and shock?
