A2B Metro Gen 2 Main Battery Rebuild Upgrade to 36V 21 ah

Test ride of 2011 Ultramotor A2B Metro Gen. 2 after a complete battery rebuild and upgrade from 36V 11.4 ah to a 36V 21 ah pack. The original battery was 7 years old and no longer holding charge. New LG 18650 cells were packed into the existing downtube battery case and reinstalled. The ebike can now do close to 40 miles on a single charge and single battery without adding to the overall weight of the bike! 馃檪 If the rear rack battery is rebuilt to 21 ah too then this ebike can have a dual battery 70 – 80 mile range…Maybe I’ll do that later but right now I can do a round trip commute of 20 miles without having to recharge at all and still have plenty of juice left to almost do another round trip.

If you need batteries for an older model, discontinued ebike, you can get batteries rebuilt at Electric Bike Marketplace in Las Vegas, Nevada: http://www.ebikemarketplace.com

E-Bike: A2B Metro Generation 2 (2011 model year). 500W Driect Drive Rear Hub Motor with 36V 21ah Lithium Ion Main Battery Pack in Downtube. Full Suspension with hydroformed aluminum frame.

    Not as nippy as your Super 73 but is it a more comfortable ride because of the front suspension ?
