Show us the display and buttons, one should be able to enter settings to change basics like speed and wheel size.

I don't know if these work the same way, with the KT you can omit the display for a one PAS level control. With the KT one links together Gnd/Black to Yellow and Red to Blue. The worst that can happen is you fry the old controller, so nothing lost. If it doesn't work buy another Brainpower or...

Just goes to prove even in retirement one can have his cake and eat it.

No only the bosh type et al and the tdzs kit, all others are cadence type which use the better current control rather then the cheapo crappy speed control. Suntour use TS with their unreliable hub control systems. Current control (torque simualtion) is not to be confused with TS, current...

Most LBS won't touch lacing a hub motor in to a rim.

Torquetech.co.uk sell Kt stuff or simply look on Aliexpress, topbikekit or greenbikekit for kt stuff.

You can't preach to some of us (the knowledgeable ones), we know exactly what we are doing and have been doing so safely for many years. For your average joe/jane ebiker then paralleling is likely not a good idea, one needs to have good understanding of how batteries work to know what you are...

Purple might be bike lock wire, hence someone has tagged a bit of Red to indicate live 5v.

Not surprised it is damaged arriving via TNT.

If you want TS mtb and not a tdzs kit, then you will have to buy a branded closed system bike like bosh, yamaha et al.

I parallel a 23.2ah/80a & 17.5ah/100a together total poss current is 180a, the current is drawn from the pair with obviously one supplying a very slight higher current. Both batteries voltage reduction is steady and much in sync with each other. I have two Swizz's the first one Jimmy replaced...

It doesn't matter which motor kit you use, you have to match the battery continuous operating current (not the peak out put current) to the kits controller. So before buying any kit one needs to know the controllers current specs. Any controller for that battery should be no more then 20a...

Out of stock though. Built-in Fuel Tank Bike Frame | Bicycle Motor Works

Definitely change handle bars to wider ones and better still get some swept back at about 40 degrees for real comfort and control, fit ergon grips and one would have a very comfy set up and little need for suspension with fatter tyres.

Another happy customer we I have helped out ;). I also had to like the post as my name was mentioned :D, now my hat doesn't fit.

It won't matter which rim you use , the spoke breakage is down to the wheel build quality more then components.

How do you find the TDZS Sturmey ? I know the 2 Pete's say the 48v is the dogs compared to the 36v, so apart from the Blue gear that some have issues with any other probs ?

But he's not an ebike or kit specialist like us.

To bring the thread back on line a bit go the full hog F & R hub with a GNG in the middle.

I wish it was, but love the iconic style and look of the bike. It is unique. The mid drive brushed Heinzeman motor is 270w and the controller doesn't speed limit. No display is used as the bike has no PAS levels, it rides as fast as the rider wants it too.
