Can this be used on a bike with training wheels?

Yes ... Even big wheels.

Is it that difficult to have to labor oneself to peddle a bicycle? No wonder this country's going downhill - people are taught not to do anything for themself... no wonder Obama is leading in the polls.

80cc? do you need a license for this?

In for three.

I bought this last month and have taken it on several highway trips.The only problem i have is with the big rigs and the wind blowing me off the highway.

If your planning on using this on a kid bike make sure you have enough clearence as this takes up quite a bit of space.

These are like fat chicks, they're fun to ride on until your friends find out.

Can you do burnouts with this motor kit?

#9 Burnouts do you with this motor.

These work great for friends with DUI convictions and no license because in AZ if the motor is under 100cc then you don't need a license or insurance. And as an added bonus now the guy on the bike gets to find out what it's like to be chased by a ton of car where the driver may or may not be impaired but is still crazy dangerous. Lesson learned, priceless!

Seems quite dangerous to me. Up to 40mph on bicycle wheels -let alone on a kids bike!

wow. i would love to have one to get to school. too bad my campus does not allow any type of motor vehicles, bikes, scooters or skateboards on campus. it would have made my life so much easier.

If it come with the airplane wings accessory kit I might be in for one?

I just got mine and was able to jump over 14 cars with my bike.

Don't Hells Angels use these?

#13: You can turn off the engine and pedal the bike on the campus.

Math is off.
$140 - coupon code handheld10 [Exp 12/31] + $13 shipping = $126 shipped.

Should be:
$140 - coupon code = $126 +$13 shipping = $139

put this on one of them chopper bikes would be cool, eh?

Well, it would be a very good tool to ride it inside any big compus,in case late for classes.
