wat

I hope this guy is dead now.

You realize there is no way that's a legit video. got to be trolling

God i hope so. I'm not even sure how i came across it. So terrible though.

AWD bike; just powers through corners at the beach nearest you

I think it's Leukybear in that there video

all for the low cost of a new lexus!









yeah i know thats yen, who cares it still sucks

Good way to get your legs dirty.

Haha nooooooooooooooo

I don't get how you turn without the chain falling off the front

"A much shorter chain goes from those cogs to yet another cog, mounted on an arm that extends from the head tube. A flexible universal joint connects that cog to another one, that is mounted on an arm that is attached to (and that turns with) the front fork. Finally, a third chain extends from the cogs/universal joint down to a drive cog on the front wheel hub."

I assume that 29,800 is the price in Japanese Yen, which works out to $250 or so, which seems reasonable for the type of bike it is.

Tretta AWD Bicycles put that lazy front wheel to work

Pretty interesting man, I would never buy one but pretty cool bikes. I read that article and did a youtube search on them. Found this video to get a better look at one. That chains rubbing your leg or pants for sure.

Well now I want to give one a ride. It would seem the extra gears and chains would just cause the bike to lose efficiency and 2wd would not in any way make it do anything better since your input power is the same, but idk

With cars and motorcycles, the performance is oftentimes limited by traction, so having extra wheels improves the traction and off-road performance.
With bicycles, you very seldom are limited by traction, and usually be lack of power, so adding the 2-WD increases weight and complexity, but doesn't necessarily help performance that much. If you got in just the right circumstances, it'd be great.

^^^ Both you guys are completely correct. It's a solution to a problem that doesn't exist.

I guess the other thing i was thinking about was that both wheels turn at different speeds which could cause some potential issues..

Not sure why that would be, since the rear wheel drives the front at a 1:1 gear ratio. I suppose there could be a problem if different size tires were used in the front and rear.

Hmm.. I suppose that is true -- In the vid it kinda looks like the front wheel was spinning at a different rate than the rear when he was demoing the drivetrain.

If that were in fact the case, then at least one of the tires would be skidding, which would completely defeat the whole purpose of the setup. Anyways, it's just a lot of unnecessary complication and added weight with no real benefit.

that's a transformer if I've ever seen one

id love to see a gopro video with dubstep of someone taking that off a 20 foot drop and the thing just exploding on impact and everyone just pointing and laughing after

Because suspension forks add too much complexity and weight!

Freds that ain't never rode a bike off-road should not be so judgemental...
