Ideas alone are not patentable, you need to have made a working device or application. You can apply for a patent during the development of your working device but you have to demonstrate your device before your patent is granted.

There is a bit of lateral play in the crank due to the design of the TSDZ2. It's because the horizontal movement is limited by 2 simple circlips. It seems bad to any bike mechanic but doesn't get worse. I would ignore it, some add a 1mm shim to make it less annoying. A shim does not eliminate...

Actually, I concur with Flecc's solution. It's the simplest to address both required torque and ease of installation. It's also the cheapest solution considering alternatives. I can build the bpm into a 20in rim for the OP.

Can you explain how the torque sensor on the to7 motor works?

The main obstacle in making a tiny nuclear battery is harvesting and controlling fast neutrons. We have not discovered any suitable materials to make the reactors vessel.

Is the sound a click or a squeak? Does it sound metallic or plastic? Is it in step with pedalling?

How long does the squeak last on average?

I did not suggest you join the brake wires directly to the controller. Sorry if I gave that impression. What I mean is you use the connectors from the loom, they are waterproof. JST SM are not waterproof.

the reason I recommend a crank drive is because it's a lot more flexible torque wise than a front motor kit. The issue for anyone with physical impairment is you need high torque at low speed. I did work on a hand bike for a guy in a wheel chair. He has one of those Weizmann hub motors. The...

I did reread the post and edited my post above but you beat me to it.

You can make your own cables. Cut the yellow connectors from the 1-4 cable and solder the brake sensor wires to them. Use heat shrink tube to seal the soldered connections.

you can fit a 4-bolt 110mm BCD adapter and 28T chainring to the BBS01. It's inexpensive. where did you read that? It's OK, I reread the story. I supplied the TSDZ2 in that kit. The steering rod was in the way and the customer made a new rod himself.

I am sure that a BBS01 kit would work well on your friend's Kettwiesel trike. I have some pictures somewhere. It can also take the Tongsheng TSDZ2: Hase Ketwiessel Recumbent Trike - TSDZ2 install - part completed | Pedelecs - Electric Bike Community A crank drive is lot easier project with...

The Ribble Low Step AL is not really suitable. The OP wants a child seat, that means she needs a proper low-step step through like the Dutch ride. She wouldn't be able to swing her leg over the rear wheel.

If you want to avoid cables everywhere, avoid the throttle and the 1-4 Julet, avoid the 9-pin motor cable too.

we can't. Most of our customers build their first kit with us, we have to make sure that they succeed so we need to keep potential problems to a minimum. Also, only Andy and me do the support job.

I am tempted to add a TMM torque sensor to the throttle of the BBS01

do keep a ear out for this.

Motor noises without other symptoms like crank slipping is difficult to diagnose. It's possible that the blue gear is damaged on your motor but the symptom of a blue gear failure is that you clearly lose traction on throttle or you can hear the ratchetting noise from the blue gear when...

agreed, at least a radiator. The TSDZ2 can reach 70C - 80 C inside after 10 minutes while the outside is just warm to touch.
