mmoncur said:Hey everybody! Thanks for all the information you've provided on this motor. Can anyone answer two questions?
1. Has anyone had experience with both a TSDZ2 and a Bosch (Performance line) bike? I'm looking at two bikes, both Electra cruisers, both with Nexus 8 internal hubs: One that comes with a Bosch 250W and 36V battery, and one that I would convert with a 48V/750W TSDZ2. Is the TSDZ2 more powerful? Less powerful? More range? etc. -- I don't really care about top speed, just the ability to go 20MPH and go uphill.
2. I weigh 320lbs. I'm assuming the mid-drives would work well for me since I could run at a lower gear, sacrificing some speed for the ability to pull my weight. Has anyone had experience with a heavy rider on a TSDDZ2?
(Assume I have a bike whose wheels and frame can handle my weight, I already ride non-electric regularly so I know how to do that.)
I have had both. The Bosch is more robust and actually lets you pull over 500 watts in bursts. You might consider a BBS02. It is much beefier, quieter and more powerful than either the TSDZ2 or the Bosch. Where the TSDZ2 is actually a 350-500 watt motor that will let you pull 750 watts for short periods of time, the BBS02 really is a 750-watt motor that will pull 1300 watts for short periods of time. Of course, you trade off the torque sensing and the Open Source firmware only runs on the TSDZ2. IMHO, the Open Source firmware is the main reason to get the TSDZ2.
