The video makes me think it's very loud and the pictures make me think it will only work on some bikes. Cheap though!

just what america needs, fat people riding bikes... think about what good you are doing your body and our environment by powering the bike yourself. You are lazy if you buy this.

they have these all over the place in Asia. works well if you have a short commute to school or work.

#2: fat people riding bikes is better than fat people riding in hummers.

prob a bit dangerously riding 45mph on a bike.

These will come in handy now that the S is turning into a third world country.

If Jan would've had one of these bad-boys she might've been able to finally take Marsha out once and for all and make it look like an accident!!!

Earlier posts on this have expressed concerns of spare part availability. Has anyone found a place to get spare parts? Pretty cheap for the motor, could be useful for other projects besides making you look like a tool while riding your bike...

Fat bacon's (aka pedoph!le nuisance_sucks) body weight is 3 times the normal people's weight. This will be going for about 8-13MPH. He's better off with a women's bike, losing calories riding it from his pink troll tent to elementary school.

Dude...awesome. I want one.

#8, who give a rat of spare parts when spare motor replacement is more than the kit.

I will definitely have to buy motorcycle insurance and a helmet when riding this on the road, especially going 40 MPH with a bike frame.

Who knows when will the frame bent out or come apart...

My old moped is only 50cc & it will go 35 MPH

Now, if only we had decent Bike Paths in most of our cites...

Be forewarned- Any engine over 50cc's is considered a motorized vehicle. You can get a DUI on your bike if it has one of these on it.

That's why they all sell 49cc versions. For drunks. Like (presumably) us.

engine size is a technicality when it comes to dui, you can get a dui on a unicycle if you so choose.

A quick search revealed that 80cc engines like this can range from 2.4 to 6.5hp. That's a big swing!

Anyone know how many hp this one is rated for? If it's on the high end of that scale it would be kind of fun to fark around with...

If you overclock the engine should you buy a better cooling fan?

Not only do these burn motor oil in addition to gas, they have no catalytic converter system, so the exhaust emitted is much worse than cars which have full exhaust / muffler systems.

Major pollution creator. 40 times the amount of particulate matter pollution as a car. EPA certa-NOT !!!!!
