Might need strong thighs. Its called the "RELATIVITY Special", if pedalled at 90 rpm, it'll travel faster than the speed of light. One full revolution of the pedals sends the bike 6 times around the earth.

Doesn't look like it has any brakes but would they even work at light speed anyway?

It is locked up to stop someone riding away on it!

Not sure the tyres are rated for 186000 miles per day.

Let alone 186000 miles/second.

Sounds like a challenge for Guy Martin......

What lighting set up would STW recommend for light speed night rides?

Hmm. If the bike is travelling at light speed, how fast are the wheels turning? Must be much faster...

What happens when you're happily pootling along at 180000 mps and your wheels start travelling through time?

Couple of those cheap mega output Chinese cree's will be fine.... just remember to charge the batteries in a biscuit tin.

Will the beam give you enough visibility given Special Theory of Relativity? Think you’d have to bite the bullet, up your budget and get some Exposure lights instead?

Depends on the sealant. Probably fine if using Stan's Race.

I'd be more worried about the fusion chain reaction it would set off?

Exposure, cheap Chinese… doesn’t matter, you’ll be overtaking those light photons anyway.

So no night rides unless there’s a full moon?

Thinking about it, a lack of light wouldn't be a problem. Rather too much of it instead.

Can it run a dynamo hub so you can keep the Exposure charged?

Fusing Chain Reaction with other stuff has been problematic in the recent past.

I think the designer needs to factor in the way air resistance increases in a non-linear way with speed. This bike will work best in a vacuum. Or at least downhill with a 4000mph tailwind.

Surely as the light itself is already travelling at the speed of light by being attached to the bike, the photons leaving said light will be travelling twice the speed of light?

Yeah, look what happened after Wiggle took them over.....

So flats and a dropper post should be first upgrades?

Nahh.... It's an education thing. The photons inside the bike light don't have the knowledge that they are travelling faster than the speed of light already. As soon as the photons are  emitted they fall behind instantly and have no hope of catching up, especially if the bike light is travelling at >c m/s. Clearly Exposure lights are a little bit cleverer than your AliExpress special, so the light falls behind at a slightly slower rate.

Has it been on a turbo trainer?

For the price of Exposure lights, I'd want them to keep up.

when they do these kind of crazy gear ratio things on utube it normally ends in catastrophic failure of the final spinning thing due to massive centripetal forces. Not sure I want to ride a bike that wants to shoot hypersonic spokes at me.

If you're travelling faster than the speed of light around the earth (assuming it's not flat) would you be better off having your lights facing backwards and using the light from the previous lap to see by?

A bugger to get started once the lights have changed, but you'll beat everything to the next set...
