I have a 36V EV Global bike "skeleton", and the Heinzmann rear hub motor responds intermittently to even direct voltage, so I suspect bad brushes or contacts. I am game to open it up. Any wise predecessors with critical "do's and don'ts", and anyone know if the brushes are a commonly available variety? I live in Arizona, USA. Thanks.

Solar On Board Recharging- Another Look? I live in Arizona, and am electrifying an old adult tricycle with 1000W motor and 48V20AH LiFePO4 battery. I am planning to add a frame for an "awning", i.e. sun protection. I estimate I will have 24in x 42in area - potential area for solar panels for on-board recharge. Most workable panels here are 12V, and I could fit 2 on the awning. Anyone out there with the brains and/or experience to suggest what I need to use the output of the panels to charge the battery, even wiring diagrams if available?? I will happily post pics if I get this beast built. BTW, I have finished updating a 24V EV Global Ebike from its 400W brushed motor and 7AH lead acid battery to 100W brushless and 48V20AH Li battery- wow! The old beast would not make it up the hill home- the new version went up at 44kph without pedaling!

From across the pond, no less- Fountain Hills, Arizona. Larry Ward, retired physician. I have owned an EV Global Motors EBike 24V since 1999. I am currently converting it to one of the China- supplied 100W48V brushless motors, rear wheel drive, and a 20AH lithium battery. I live in a hilly region, and the old 400W whiny motor and lead acid battery did not get me home! I am likewise converting 2 tandems to front wheel drive electric for family fun, and may start to convert other vintage, rehabbed bikes to electric for resale. I also play with and repair/rstore old Lionel electric trains.
