    Building trike with 5 speed hub

    I am thinking of building an e-trike from a Schwinn trike, and fitting it with a 5 speed hub driven by a non-hub motor for a small business pickup/delivery machine around town. It would have a tall (4 or 5 ft) light weight cargo box mounted in the rear to carry parts and clients computers...

    Battery performance seems to be dropping off.

    Have a Chinese 20Ah Lithium Ion battery in pvc jacket for about 4 or 5 months. Lately it seems to take longer to charge. And it seems to discharge a tad quicker than it used to. Does that have anything to do with the onset of winter and the temperatures going down to 30 or so overnight in...

    Monarch Fork Fail.

    You may remember my retro ebike build used a Monarch reproduction fork. Well I have to say it did not hold up too well. One day I was carrying a back pack full of groceries, and one side bag was full too. The fork bent right at the crown. One or two welds broke on each side and the fork...

    Anyone build a side car for their ebike?

    Was thinking about building a side car that is large enough to carry an adult. Haven't found any for sale commercially. Seems they are all custom made. Any suggestions or plans?

    project is working good. Not best, just good.

    The retro ebike is working very well. 48v battery, 1000watt rear wheel drive..... plus LED headlights and dual tail lights. Everything is cool. But lately I have been running the bike at well over 20 mph where before I have been keeping it under 12 mph to see how far I can go. Now I am...

    How big a load do you carry on your ebike?

    I have two rigid side bags (pvc molded cheap motor cycle bags) and on top of the side bags I have a very big carry bag attached with Velcro tapes to the rear carrier. There must be at least 60 lbs or more when I go food shopping. Add that to the back pack on my back, and that pushes it up to...

    After 100 miles, started hearing funny noises.

    Have about 110 miles on my project now. Started to hear a funny clicking/tapping noise at speed. Today I checked it out and found spinning the wheel off the ground made no noise, but with load the noise is there. After a bit of checking, it turns out those heavy spokes were loosening up...

    People look at me funny....

    Finished my "retro" looking eBike today. Put 20 miles on it and people looked at me funny as they drove by. I ride this same route in my road bike 3 or 4 times a week and never get more than a wave. Is it because my feet are not spinning the pedals, or because I just look so happy?

    When to charge Lithium battery.

    HI everyone! I have spent an hour searching and reading posts about charging. Lots of stuff about BMS and such, but not what I was looking for. At what point should a 48V Lithium battery go on the charger? Right off charger the battery showed 54 or so volts. After driving a while, the...

    How to get 12v from 48v battery to run accessories?

    Is there a way to get 12v from the 48V battery to run accessories without using a golf cart converter? Mainly its 12v LED light bulbs (automotive style) that I want to power and not use a separate battery. I know this can be done with the proper resistor, but I have no idea how to determine...

    Lack of thermal paste in controller.

    I opened up my 48V controller and found that there was very little thermal paste between the metal bar the transistors are mounted on and the aluminum case. There were 4 little spots of paste along its entire 6" length. How disappointing. So I wiped off what was there and coated the metal bar...

    Is it good to shorten the 3 phase wires?

    I have a 48v/1000w rear wheel kit I am currently installing. Because of where the controller will be mounted (in a hard saddle bag right near the axle) I can cut at least 20" off the 3 phase wire lengths. From the axle to the controller will only be about 12 inches. 1) Should I shorten...

    My Retro look eBike project.

    Hi Everyone! I am new to ebikes, and thought I would share my project. The bicycle is a 1990's Huffy department store mountain bike. Two years ago I completely stripped it of all components and rebuilt the frame as a retro looking cruiser with Monarch spring fork, 2.25 x26 Kenda tires...
