Re: Recommend a rear sprocket size for TSDZ2 and NuVinci

I went with a 14t sprocket and a 52t chainring. While I was at it I also installed a BMX chain, but that has little to do with speed. Before the change, I was basically going about 17mph. After the change, I am easily hitting the low 20s'. Sure, on long runs it would creep up into the low 20s' befor...

Re: My next e-bike build - BBSHD with hydraulic IGH

It is interesting, I am going to admit that something in me was hoping that you were working on a hydraulic replacement for the entire chain drive system. Pressure hoses going from the area of the crankarm back to the IGH. I don't know of it being done, but bicycles have been around long enough that...

Re: Tsdz2 advice

Can I suggest riding it stock for a while to see if you have any issues that the new firmware will address?

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?

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 tyres on,...

Re: Grinfineon 25A Blinking red light, no power

First, I don't want to speak poorly of a forum supporter. I have come to the decision that this motor is not going to do what I want. I am switching things around so that I will use a bafang mid-drive and a Nuvinci in the rear. This is basically the setup I used with my previous touring trike. A big...

I got a message back from Grin. They said that the blinking light indicates a brake circuit fault, which is different than what the manual says, I unplugged the tripwire and the problem is still there.

Re: Grinfineon 25A Blinking red light, no power

It is a single slow (.5 sec on, .5sec off) flash. This is what the manual says:
LED Slow Flash - Controller powered up, throttle is not pressed or it is running but in sensorless mode
I looked around to see if I have another throttle around, I don't. Any troubleshooting tips?

Re: One stop for solar charging ebike info?

When I built my solar touring trike I planned on a road speed of 13mph. That came very close to what I really experienced. I question those who say you don't need a large battery. There are a lot of stretches of road that have a lot of tree cover. I also needed to have the ability to dip into the ba...

To let people know where this went, I ordered the kit with the regular winding. It is now installed and has gone for a couple of test rides. My first observation is that it is too fast, even with the regular winding. The Rotovelo is an unsuspended Velo and anything but the smoothest of roads is unco...
