There’s a lot of thought gone into the product, the presentation and the detail. It’s a nice feeling when the power kicks-in as well.
The package essentially contains the motor wheel, the battery, wiring and its handlebar mount, the magnet ring and sensor that reads whether the pedals are turning. Assistance is slight on power setting 1, and just nice on 3.
My issues were:
The battery has a master on/off switch - the instructions stated you could locate and flick this from outside - I had to undo the battery cover to do these: not sure if it charged while in the off position - charger unit light was red, suggesting yes
I needed to do a fair bit of filing of the dropouts to get the axle in;
I didn’t measure the internal width, but 622-28 is the minimum tyre width I found I could mount. 25s were floppy, even a Schwalbe Marathon;
The valve hole is on the large side - might accept a car type valve;
The instructions for the magnet ring make much of the gap between the L/h crank and the bearing: if you’re running Shimano there is none - but all you’re doing is attaching a double-hinged arm to the inside of the crank - the hinges then allow you to position and angle the ring appropriately to make contact with the sensor; You secure the arm on the crank so the ring traces a decent circle when you turn the cranks
I mounted my sensor on the seat tube because of an oval / oversized alu down tube which would have positioned it too close
For the longer term, while the wheel and battery/mount feel robust, the plastic magnet ring assembly, all held on by cable ties all feels a tad flimsy for my liking.
