After riding 300 miles on the #Cetma to break in the #Tongsheng motor, I’ve switched back to my #Workcycles FR8 for everyday rides. The difference in comfort is astounding - the FR8 rolls along on a cushion of air. And being fully upright again means my wrists and shoulders are suddenly much, much happier. #BikeTooter #CargoBike #ebike

Finally got the battery for the #Tongsheng #ebike motor mounted where I want it. The cargo platform flexes a bit under the battery so I need to add some kind of additional support. Took the front box off for repainting. #CargoBike #ebikeConversion #BikeTooter

Here's what the #Tongsheng #TSDZ2 install ends up looking like on my #Cetma #Margo #CargoBike. I haven't cleaned up the zip ties yet because the battery is only temporary (I'm going to get a smaller one that fits better).

Instead of the standard anchor bracket, I screwed a chain tensioner into that anchor bolt hole (https://cycles.eco/collections/tsdz2-accessories-parts/products/chain-guide-for-tsdz2?variant=) because eccentric bottom bracket + chainstay. There's some foam protecting the frame in case the motor moves.

Rode around town testing the Tongsheng motor on the Cetma cargo bike. Did great tackling hills I would never ride without a motor It was a chilly 28F but nice and sunny. #cargobike #tongsheng #tsdz2 #ebike #BikeTooter #Provincetown

Tons of progress today on the Tongsheng motor install on the Cetma cargo bike. Tuned the eccentric bottom bracket for better clearance of the motor, zip tied the speed sensor, and figured out which side of the chain tensioner the chain goes on! Put the cranks and pedals on and plugged everything together. Test rides were great fun (even though it started raining). #cargobike #ebike #BikeTooter #Tongsheng #TSDZ2

oh baby

I want to add a mid-drive motor (#Bafang or more likely #Tongsheng TSDZ2) to this #Cetma:

https://social.ridetrans.it/@Andres4NY/109468987375343649

It has an Enviolo/Nuvinci rear hub, and an #EccentricBottomBracket to tension the chain. I don't really want to switch away from the Nuvinci to a derailleur, but the motor will most certainly not permit the eccentric BB to move & will be replaced w/ an adapter.

Any else done this, and have a suggested chain tensioner model that will work w/ this kind of hub?

Does anyone have hands-on experience in e-bike conversion using the Tongsheng TSDZ2 kit?

I have the urge to convert my Orbea Alma XC bike with that kit, but I want to know of potential gotchas from someone with first hand experience.
