should i buy an xb-500 electric bike to got to work?

Answer 1

Absolutely, (as long as you're within 15 miles from your work) - any time we can find something that will save the environment - I say, go for it! Plus they're pretty nice looking.
But I would first check your state motor vehicle laws before buying it just to be sure that you can drive it on the roads. Some states are funny about electric mopeds and scooters.
If you're in Canada (at least in Ontario) some electric bikes/scooters that have operating pedals don't even have to be registered.
Also, don't pay much over $650 (with shipping). This site has the best deals and shipping is low,

Good luck to you!
