I am designing an electric bike for commuters to use day in, day out. I am asking you guys who live on the outskirts of cities to give me what you want in the perfect personal transport. This product is made for the masses and made by the masses. Any answers will be appreciated and taken into account. Thanks all!


Answer
1) Price
2) Range
3) Recharging time
4) Speed
5) Battery life
6) Comfort and carrying capacity

Price and range are the most important

Any suggestions on a great electric bike?
I want to get a bike that I can pedal and goes maybe 20 mph??



Answer
I bought one recently, but it wasn't top quality - actually it was the cheapest I could find. The E-Zip Mountain Trailz. It's actually pretty good, but the realistic range is only about 13 miles.

I've heard that Giant makes some really good ones:

As does Currie Technologies. They make both the E-Zip (cheap version) and the i-Zip (higher quality).

The main things you want to look at are range, battery type, and weight. Obviously lighter and longer range are better. Mine claims to go 15-22 miles/charge and only gets 13, so performance may not meet the claims. I think the range claims are based on biking pretty slowly.

Sealed lead acid batteries are the cheapest and most economical, but only last about a year. Bikes with NiMh batteries last about twice as long, but the battery costs about 3 times as much as a SLA battery. Lithium ion batteries are very expensive but last a very long time.

Good luck.
