Thanks! What do you recommend as an alternative to the Ultra Juggernaut at roughly the same specs/price/performance? I am considering the Surface 604 Rook, Giant Road or Roam, espin Nero, electric bike company Model R, and MOD Berlin Any suggestions.

Thanks for the replies…..but is there a way to verify which type drive motor controller (UART or CANBUS) is on the bike? Also, the on line sales literature says that the Ultra Duo 2, with the M620 1000 watt motor has both cadence and torque sensors. How does that work. Thanks again for your help.

I am looking at a new Juggernaut Ultra Duo 2. Does this CANBUS isuue apply to the Bafang 1000 watt motor in that model? I am new to e bikes, and will be mostly riding on roads/smooth trails, no real “off reading”. Thanks for any update.

Thanks for the advice jo, it is appreciated! Yes, I have revised my selection criteria to stay with a step thru frame, and easy flat foot for my 32” inseam. The Surface 604 Rook is the leading candidate, with espin Nero and Ride1Up 700 runners up. Any feedback is welcome. Thanks!
