Overall Product Rating 5 / 5

Good product for mid-motor on Tandem

By Cengiz

5 / 5

I recommend this product

ConsShipping cost from UK to Switzerland was almost same as the product cost!

I installed them with Bafang BBS02B 500W mid-motor to a Racer 3000T Aluminum frame Tandem. I had to remove back Truvativ ISIS bottom bracket and crank-set.

Would be nice if:
1. the bottom-bracket mounting holes were in diamond-shape.
2. 20mm offset option on the left-crankarm with spider.

For the 2. problem, I ordered a pair of 20mm Bicycle Pedal Extenders from Aliexpress, waiting for them. I will install only the left one to compensate right-crankarm's offset issue...

Useful to install a mid motor on a tandem

It will be helpful to have an option for rigth arm with 20mm less offset. Impossible to find with square hole at 0 degrés.

SJS Customer Service:

This very much depends on your frame, the OLD for the rear hub and the chainline you wish to achieve.

1 x 9 single speed?

By Mark

22 Jan 2019

Can I use this as the basis for a 1 x 9 single speed 104 b/pcd on MTB with 68mm English threaded BB please?

SJS Customer Service:

This one is for tandem. The chainring is on the left.
Hope that helps.
Thanks
