    hello how much cost of fast4ward edge ebike batteries

  • EBike Marketplace: July 09, 2020

    @Jules – Yes, our rebuild service should fix this. We’ll be in touch with our recommendations!

    I just bought this bike used and the battery seems to be working fine. However, the owner had it in storage for about 3-4 years. It’s giving me about 25 miles per charge, but the manual says if there is going to be long term storage and the BMS is turned on it can permanently damage the battery. Should I be concerned? What is this permanent damage? Is it something this service/rebuild could fix?

    @Robert – We prefer to re-use the existing BMS if we can.

    Hi, I have a fast4ward folding bike with a failed battery. When you rebuild do you use the existing BMS or replace with modern. If you replace, do you retain all the bike functions? I was thinking about the 2 supplementary connections from the BMS to the bike via the 4 connections on the battery holder.(don’t know their function)

    Thanks Robert

    I have a Kuo A2B that uses the exact same battery as shown in your photograph. What is the fee to rebuild it?

    Thank you.

    @Ido – We do not recommend changing the voltage of your battery. We do not stock new A2B batteries.

    A couple of years ago I purchased a a2b kuo 24v/12a e-bike. I’m looking into replacing the battery, I was wondering whether the 36v battery will work with my current bike? if yes, do you have one? how much it will cost? and can you ship it to Israel?

    Thanks

  • EBike Marketplace: July 08, 2019

    @Larus – We can rebuild your existing batteries if you send them in to us, but we do not stock this battery.
