Followed by choosing the right power for you. As a city commuter, then select a 250w kit. When it comes to mountain cross-country, you can choose a higher power.
Finally, confirm the mileage of a single ride as a way to choose the correct battery.

TongSheng TSDZ2B Mid Motor Electric Conversion Kit | Kirbebike
Early days and sure it is a great product, but after first 17miles had a problem with pedal.axle bearings. Hope to get issue resolved soon and back out again. Wanting to ride all the canal tow paths in GB!
My order was shipped on 4 July and received on 7 July very happy with the service. Very happy with the communication from Jason for keeping us updated all the way with the order.
The drive was fitted to my son’s downhill mountain bike, light ali frame 9 speed cassette with quick shift and he is very pleased with the way it works ad how the smooth power comes through.
A very happy customer and would recommend fitting this kit.
I may try the 100watt hub drive for the next one.
The TSDZ2B is a fab bit of kit. I went for the 500W with a 48V17.5Ah battery. From buying to arrival the coms from the seller were great and kept me up to date every step of the way, with proper tracking etc.
Installation? Yeah was way longer than the "20 min" you may see some claim but in real world conditions on older bikes that haven't had a lot of love things seize up.....soooo took myself and a friend about 4 hours to unseize everything and fit it all properly and have it all wired in neat etc etc.
Love it and only issue i've had up to now is my older aluminium chain kept breaking, a new steel one later and been great ever since.
Highly recommend these kits, sure you can take a few hours (4 in my case) to get it done and i wont lie, there were lots of cuss words going on, but overall i'm so happy with the end result.
Its certainly given my bike a new lease of life and me a new love for biking. For my needs it works really well, also the price of the kit and battery were the cheapest i found.

EDIT** Done nearly 100 miles now, still love it, however... I have had issues with the motor literally vibrating itself apart screw wise, every screw came loose at some point or another, even the small ones put on the motor cast by the manufacturer etc, was nothing a bit of Loctite Blue on all the bolts couldn't solve but be warned it can and does happen. Oh also the fixing block came loose so i used a much longer bolt than the one provided which solved that problem, the provided bolt doesn't get much grip on the thread due to its short length, again longer bolt solved that issue.
All in all i'm still super happy and use my bike a lot more than i used to, up to now 100 miles more. :-D
EDIT2***
So hit 120 miles going on a lot of off road trips putting the motor through some tough tests, i'm happy to say its passed with flying colours and nothing has come loose etc since adding the loctite blue to the screws etc.
Added a few pics, dirty as its lit come back from a very muddy ride, motor did very well.
