I have put together several nice gas powered bikes but the quitness, no gas or oil is a treat because of the overall cleaness. So far I certainly like the quietness of the bike.
Ezip electric bike battery trial#
I bought the Ezip kit and installed it on my bike just for a trial with Electric. Here is what I have in mine: Find a strong brushless replacement motor that will handle the voltage and buy a second set of batteries, but Lithuim this time. As was pointed out by Motorbike Mike and Neon the 36v will shorten the life of the motor. So far it is doing just fine and the motor does not get hot, just a little warm. The bike tops out at 22mph as was said by one member and that is fast enough for me.
Ezip electric bike battery plus#
Wired the the bike for 36v and as suggested, bought three 12v 10amp SLA batteries from our local Battery Plus store. This is partly a learning process for me so hear what I have done: I purchased a 36v controller, thumb control and charger. Most of the better high tech battery makers do include a built in battery management system and a small 2 or 3 Amp battery charger, with an optional higher rate charger available at extra cost. To change to higher tech batteries you will need to make sure they have a battery management system built in or buy a separate battery management system and you will need an appropriate battery charger. They last approximately 4-6 times longer than SLAs, weigh about 1/3 of what equivalent SLAs weigh, and are about 1/3 the size of equivalent SLAs. I went with the more expensive LiFeP04 batteries from Ping. Get in touch with Curry to see if you can increase the voltage to their motors safely.
Adding another 12 Volt battery in series to increase your voltage from 24 to 36 will be heavier and greatly improve your power and speed, but may quickly burn up the motor or at least shorten it's life drastically. Adding higher Amp batteries will increase your range, add to your weight, but not otherwise increase performance and with no danger of harming your motor. The e-bikekit direct drive hub motors I am using are designed to take voltages from 36 to 72, but I'm not sure about the Currie Ezip motor. With battery power, Volts equal speed and power, Amps(or Amp hours) equal range(distance) you can travel on a charge.
