To those who own a e-Mtb, what have you got and what don’t you like about it ? If anything
When you say intergrated with Di2, what do you mean ? Does it auto shift or something ?I have one actually! I have a bit of a dodgy knee, so gets me out more often especially if I need to test something.
Focus Jam 2 . Love it! Shimano system, mine is integrated with Di2. works a treat, 19kg. Not as heavy as a Levo etc.
If you buy a bike with a shimano motor Di2 will plug into it and use the same battery and display. Nice and integrated. Not that Di2 is "necessary" But hey, I can write it off as a business expense for tax and wife, so why not!When you say intergrated with Di2, what do you mean ? Does it auto shift or something ?
Hope it keeps a reserve, imagine riding a flat e bike with no gears. Roadie di2 went flat once (kids playing with shifters, kept trying to shift on the stand), that was bad enough.If you buy a bike with a shimano motor Di2 will plug into it and use the same battery and display.

I've tried a few:
- Bionx. Best of the bunch but super expensive.
- Shimano steps 250W. Not as good as BionX but better than all that chinese crap. Feels like a lot more power which would lead me to believe that the chinese/Australian lumens conversion factors also apply to ebike watts.
- 250 bafang. Pretty slow and the kick on and off annoys me. This model works better in throttle but lacks in power.
- 500w bafang. Reasonable power and the kick on and off is even more annoying, however most people who use this run throttle mode. obviously no road legal.
- 1000W bafang. Same as above, just more power.
- 250 Tong Sheng torque sensing pas. Smooth power deliver but simply not powerful enough. Literally feels like half the power of the shimano steps.
- 350w Tong Shen torque sensing pas. This is what I actually own and it's got about the same power as the shimano steps but with a torque sensing which is great. However power levels off very quickly as the motor rpm is not optimum at high cadence. This is where th eBionX and steps are much better.
It must hey. Because I have had the battery go flat enough to stop assisting the motor, but it still works the gears.Hope it keeps a reserve, imagine riding a flat e bike with no gears. Roadie di2 went flat once (kids playing with shifters, kept trying to shift on the stand), that was bad enough.
Back ot, the focus Jam looks like a good option, decent range, weight and travel.
This has been helpful in my ponderings on building an ebike for a hilly 60km return commute out of an old Giant 26" hardtail as my next project.
Interested to tap into/hear your thoughts.
Is your 350 TS 36V or 48V?
Where there are options, any comment on desirable voltage, and why?
Any comment on batteries: quality, source and cost considerations v performance and range.
What chainwheel and wheel size are you using?
