[Closed] Propain Yuma

I don't have any experience of one aside from photoshop layups with every other 24/26 kids options.
I like it in 26, but in 24 its too long in the rear center and to long out front. It gets better with 26 wheels, but you'll need to add wheels/dropouts at another 225eu
The specs say its boosted but I think I emailed propain and they replied that its 142.

I'm not sold on the need for 140+mm at 24" size either and every bike has its build spec faults. 155mm cranks are too long for a small rippers "DH" bike. 155 is to long a with too much travel and too heavy for a trail bike too, but that could just be my opinion.

Great looking bike though and I bet it goes real fast if the kids got the cojones to let it go from the top of the uplift!

Åre bikes here in Sweden rented them out at the local bikepark. They looked decent and their website says they are for kids between 125-152 cm, if that helps in any way.

Thanks for the replies. My son, as he puts it, only rides park. Hates uphill with a vengeance but we live in wales so up at bike park wales every weekend and he’s doing really well. I’m looking at the 24/26 bikes of which there are only a few as he now needs full suss having ridden rigid for some time then we put some front suss forks on and that made a big difference. Any other parents out there have any views or experience with the current range of kids full suss?

cheers

just building a new 24 HT for my son.  looked at the current range of FS bike and decided they were too expensive and heavy for his current abilities.  I wouldn't bother with one of the large travel bikes unless he is actually going to make use of it.  Liked the look of the trek jr or the norco fluid.  The ripcord is got decent geo too.  What ever bike you get the fork/shock will need tuned.

Still got a few bits to fit but will be ready for xmas.

Well my son is having coaching at bike park wales every weekend and is riding blues and reds confidently and the occasional black section. Like all parents cost is an issue which is why I’m looking at the 24 convertible to 26 range of bikes so we can get more life out of whatever we buy. He rode every blue on a full rigid and it’s lack of suspension that’s holding him back a little. Not to concerned about riding trails but he absolutely loves the bike park and his current ride has been well hammered

I'm not quite sure why bike companies do the convertable between 24 and 26 in wheels thing on kids bikes.

It doesn't change the frame sizing at all.

Putting 26in wheel will just raise the BB a bit.

You'll then end up having to fit longer stems to get the bike to fit, which isn't ideal.

For a kid who "only rides park" I'd be looking something like this:  https://www.commencal-store.co.uk/clash-24-c2x26592860

How old, how tall?

Two other 24/26 bikes are

Rocky Reaper

NS Nerd JR

Both are compromised in 24" mode though and you're going to make it more difficult to develop certain trail skills on a long rear end. BUT, if he can get it sorted then once he's on a dialled geo bike he'll crush it!

Flow kids bikes out of the USA are trying to solve the geo changes between 24/26 with adaptable reach and dropouts but I not sure it'll every get to market.

I'm not sure how much you actually increase the bikes useable life span with 24/26 as you shorten the 26wheels life because the front center is too short to be useable for as long as the wheelsize would be on a bike designed only for 26.

Tough one this.. I totally get you pain.

I'm going through equally challenging choices trying to get the right follow on bike to my kids ripcord..it has to do Whistler bike park and squamish and Whistler trail riding and xc racing!

don't get the Rocky Reaper here in the UK AFAIK.

I had the same quandary last year with my lad..... Tried him on a few xs full bounce bikes and after talking to a guy at TF tuned I decided to not to bother with the full sus. I just opted for building a xs Ragley blue pig for him.....he also 11 years old and weighs about 2 stone dripping wet.lol. By the time I bought a shock and got it custom tuned to him it would be £250 and he will more than likely have grown out of the frame in 12 months. Do I'm saving my bucks until he puts a bit more timber on then I will go down the full suss route. You can get some bargain frames on Bikediscount.de to build up.

Thaks Bearback Son just turned 11 and is 1.45mrs , 4ft 8 inchs tall with a slim frame, hes built like a racing snake. One of our localbike shops have recently done a 24 to 26 swap on anoter customers bike and they ell me that its been no problem at all. I cant afford a 24 which he will only use for a year before needing to change again..
We are both new to the sport and the technical aspects are a nightmare with so many different views on what works , what doesnt, the right geometry, all changed from my youth when we just rode whatever we could get our hands on. We shall keep looking for advice and thanks for those who have

Tanks for your help. Mines been trashing his hardtail in the last 2 years, did all the bluies at BPW when it was still fully rigid and it was only on the last section of Terrys that his forarms gave out. Changed the fork and thats helped but folllowing him down Vicous valley for example can be scary to watch as the back ends all over the place especially on rocky and rooty sections. I also have to add in the peers factor as all the kids in his coaching group are riding full suss now and it definetly helps with skill progression, well it did with me but its only been 2 months since i went from hard to soft,fnarr.

lol.... I know what you mean about watching his back wheel bounce around. He's not had the pleasure of riding BPW yet but I can see what you mean if your riding there regularly. I'd have a look at buying a XS 650b bike and put some 26" wheels in it if the 650b wheels are too big for him.

At 145cm I wouldn't be worrying too much about 24" wheels, hes pretty much past that size.
Straight to 26 junior bikes for the full bounce. He's big enough to run 26 and the bigger wheel will help keep him out of the breaking bumps.

I must say that the Yuma is a darn nice looking bike though!

Thanks folks I hadn’t thought about his height but looking at sizing I can now look at an xs frame in a youth specific bike. So now the next question is any recommendations for youth bikes?
