    advice on new build

    I am considering buying the bike and adding a motor. I am looking for feedback if this is a bike that will accept a hub motor without problems. It is an aluminum bike so torque arms will be needed. All thought are appreciated. Also I'd like an opinion on the frame in general. Thanks, Harvey

    I use andersons for heavier wire. But I need some connectors for 20-22 g wire. I am using spades and hate them. There is a high headrest on my trikes seat. I've attached a grin red blinking light to the headrest. From time to time I remove the seat for various tasks. The tail light wires need a...

    battery confusion

    I was recharging after every ride. Most of my rides are 8 to 11 miles. I have 20ah battery for the occasions I want a long ride. I have read here that it is not good to leave your battery fully charged. But for how long? I might ride consecutive days and I might not ride for a week. If riding...

    What is that noise?

    I have a 3540 crystalite hub motor. I notice at low rpm's that there is a vibration coming from the motor. It is almost an harmonic vibration. And I noticed that on right turns at low rpm's and accelerating I hear the noise. But not on left turns. Is this cogging? Any thoughts? Thanks, Harvey

    Ebike mechanic list

    I noticed a plea for a mechanic in the LA area. Makes me think we need a running list. If it is listed on any site it should be here at ES. Where else? Almost all bike shops can't help. There is no opportunity near me. I don't think there is anybody nearby that even knows what an Anderson...

    CA instructions for dummy's

    I read the manual a few times. It is not easy if you do not speak the language. I finally change it from kph to mph. It still required circumference of rear tire in mm. Got that too. But it was not easy. It seem to be written for multiple models. Not a good idea. Each model should have its own...

    Start of my second trike build.

    My almost new trike. It has 200 miles on it. It is an HP Scorpion fs 26. German made. Full suspension. The first step I think was the toughest step. I have a 3/8" x 11 x 13 plate nicely installed below the seat. I was the helper. I don't weld anything. Still making it happen was like a marathon...

    I like bling and accessories. I will have a 48v battery on board. I will also have a converter to 12v. I want to build a compact power strip in a quality way. I want to be able to power as many as 5 separate devices. All low amp draw. I have no idea where to start. I could not find a 48v to 12v...

    Which hub motor?

    I just got my new to me trike. An HP scorpion fs 26. I want to find the right hub motor. I want top end speed more than a fast start. I'd like a top end of 30 to 35mph. I think that means 48v and a 750 to 1000 watt motor. I live in flat florida. I'm thinking no gears. I have a 135mm dropout...

    Just bought it. I'll have it in a week or 2. My second trike. I previously had a Catrike pocket. Had a 750w hub with 48v 18ah battery. I think I would like the same basics. I hope to be able to maintain its ability to fold. I'm looking for thoughts and ideas for all the parts and pieces. I'd...

    Recent concerns of lithium ion batteries

    And previous issues with the 787 dreamliner. It seems to me that when the press writes about any negative issue they never indicate the battery chemistry. They write lithium ion. In the final report on the dreamliner I found a tiny bit that gave correct info of the chemistry. LiCO. I like the...

    Our town bought a double size golf cart to encourage down town business. The parking is tight hence the big golf cart. It has a big solar panel on the roof. It is equipped with lead acid batteries. Will the solar unit cause the cycle number to be very high due to the intermittent charges? My...

    Post your distance on the life of your battery

    This is not a contest. And this is not scientific. Just an indication of how far your battery has gone. Including info on those batteries that are used up and those still in service. We all know the smaller and slower go the greatest distance and pedaling changes the outcome. Nonetheless it...

    hub motors, effeciency & longevity

    I've noticed that on my hub, approaching 4500 miles, the effeciency of watts per mile has been slowly droping. Perhaps it is my driving style changing but I don't think so. Perhaps battery but I don't think that is it either. My guess is that as the parts get used in the hub the effeciency...

    confused on fuses

    A few montha ago, after a kff, and the battery stiil good I figured I better put an inline fuse on. My max discharge is 29 amps according to my CA. So I installed a 30amp fuse. I wanted to see what happened if I discharged higher than the fuse. For test purposes I swaped the 30a fuse for a 25a...
