Good to hear you figured it out and got it running, Yes, you have to get those controllers started.

I probably have done close to 20 conversions. I had not owned a new bike since my 1975 Gitane 12 speed. In 2015, I bought a new GT hybrid, and saw an ebike on display. I bought one later for my wife, and after seeing how it was put together, I converted an old 1990 Trek. I kicked off my...

Welcome to the forum. Not too many conversion posts on this site, so always glad to hear about them. There's a forum section for DIY that's mostly empty, We'd all be happy to see pics of your projects.

Dual controllers. One throttle with +5V from one controller. Common ground. Throttle signal shared? Should work. Make sure each controller runs separately first. You already did that with the single throttle?

I use an Atorch DL24 load tester to test battery capacity and also to discharge them to a specific voltage. In this picture, I was discharging this 42V cell array to 2.5V so it could be taken to a recycler, I use the Atorch to set my spare batteries down to 3.4V/cell. That's about 30% state...

I've never purchased thru Alibaba. Instead, I purchase off aliexpress. I have filed several disputes with Aliexpress and always had a good outcome. I know the two companies are related, so perhaps the dispute process is similar,

Very good work on your part, but beyond the scope of most members here. The Germans on the Bosch forums will probably love to see your data,

Illinois just reaffirmed the 3 class definitions to be treated like bicycles, Anything over 28 mph is a moped (license and registration time). Class 3 is pedal assist only, This was apparent in the original law passed about 8-10 years ago, but dealers were trying to sell throttle limited to 20...

While I got used to the original 3 speed PAS in my Trek conversion, it was, face it pretty crude, after I started riding torque assist on the TSDZ2, I had a five speed controller with a smoother pedal assist although it's still cadence based. I switched. While the original 36V pack still slides...

In 2015, I bought my first bike from a shop in Madison, WI. They had a fire from a battery that winter and almost 100 ebikes were damaged.

I'll review my original analysis 11 years ago. I knew I wanted a rear motor because I didn't want the front motor spinning off the bike and me faceplanting, I wanted to pedal, and direct drives have resistance from the magnets when you pedal with the power off. A rear geared motor will coast...

Do you take Montgomery Road or ride thru the subdivisions? Pretty busy at rush hour,

Hub motor vs mid-drive — For a fairly normal bike, what usually makes you choose one over the other? Is it mostly terrain and climbing, or are reliability and maintenance just as important? Originally, it was price. A Bafang BBS02B was over $500. The CYC's twice as expensive. Hubmotor kits with...

I've done geared hubmotors front/rear plus mid drives. I've also purchased a few inexpensive but decent ebikes. Been ebiking for 11 years. It was originally cheaper to build/convert but today, if you watch for closeouts, you can often buy a better featured ebike for less than the price of...

The perception, according to the New Jersey ebike shop owners, is that ebikes are banned. Their sales are down as much as 90%. Where I live, Illinois, ebike laws have clarified class 3 per the original people for bike definitions, and added age requirements to keep young kids from riding them...
