    The Priority Current (review here) is close to what I want: Belt drive mid motor hydraulic disc brakes reasonably clean looking Comes in a variety of sizes (Important to short riders) As a note, it uses the Truck-Run motor, which I know nothing about. I am a bit concerned about the long term...

    12V Battery system for Small Travel Trailer

    I recently got a small Travel Trailer, a Casita 17' and I am thinking of adding a Li-Po and some Solar panels. I have about 370W of solar panels, from another project, lying about. I will need a 12V battery and controller. I am aware that I can use the Lead-Acid batteries that are currently in...

    Looking for Vespa Elettrica reviews or opinions

    I have an ebike that I built, but I am looking for something a bit faster and a bit more refined. I do have a motorcycle license and experience. I had an electric scooter for several years in Asia. I have been giving thought to the Vespa Elettrica and the new Sonders motorcycle. The Sondors...

    Have you licensed a Sur-Ron?

    I have looked through the giant Sur-Ron thread and I do not see answers to this question. Have you licensed a Sur-Ron? If so, in what state? What was the process? How did they deal with the VIN issue? Any other details would be appreciated. In the state I am in there are two blocks to getting...

    Recommend a rear sprocket size for TSDZ2 and NuVinci

    Yesterday I was working on my commuter eBike. There were two things I wanted to accomplish. The first was to switch from 27.5" wheels to 26". The other was to install a NuVinci hub. I had the Nuvinci built into a 26" wheel and all of that was ready. Most of it was the little stuff, putting...

    Do e-Bike Controllers make noise?

    I realize this is an odd question from someone who has a couple of ebikes. However, I am installing a kit on my velomobile and the most convenient place for the controller is right behind, and to the side of, my head. I haven't noticed any noise from the controllers on my other bikes. However...

    Please review this before I place an order

    This is going to go an a Rotovello (a moderately heavy velomobile). I also have a 48V 30AH LiFePO4 battery that I will be using with it. My goal is not high speed, instead, I am looking for range and the ability to pull a trailer with solar panels. I already have the solar panels and charge...

    Poor range and randomly shutting off

    A couple of years ago I installed a front, geared, hub motor and a bottle battery with a built in controller on to my commuter. At this point the batteries are, pretty well, done for. It gets used year round, including sub-freezing temperatures. The battery is not giving more than about five...

    BBS02 turning off can speedometer be bypassed?

    I have a BBS01 on my trike. The trike part is important because to make it work I had to extend the speedometer cable, to do that I soldered in a length of cat-5 that I had lying about. At this point something has gone wring with e extension because the speedometer is not showing anything and...

    Looking for a roller style e-bike what are my options

    First off, you have three threads that all, essentially, ask the same thing. However, to answer your question, most here are likely to tell you that you are going to get the most B/B by assembling your own instead of going with ah pre-built e-bike.

    Best mid drive for extended, legal power limit, reliability

    Having finished my commuter e-bike, pictured below, with a 36V geared hub motor; I am preparing for another project. The next plan starts with my trike: I am planing to go mid drive. Stage 1 is to get the trike working. I hope to do that this year. I mention stage 1 because there is a...

    Battery care in the cold

    I am a teacher. As such my bike sits outside all day. The first time I really noticed the impact of sitting outside all day was a day it never got above 20f (-6.67c). On the ride home the battery read much lower than usual. Since then, if it is not projected to get above freezing all day...

    In praise of front hub drive (ice)

    These last few days I have noticed an unintended benefit of choosing a front hub motor. As was mentioned elsewhere, the reason for my choosing a front hub motor was because I happen to like my NuVinci rear hub, ruling out a rear hub drive, and the bike has an eccentric bottom-bracket, ruling out...
