My Radrover arrived last night - with a Bafang - and I took my first ride this morning! BIG difference from my Sondors - I used 50% of the battery on a 15 mile trail loop that regularly kills TWO Sondors 8.8Ah batteries. Having lower pedaling gears helps a LOT. I also like the cadence detection, its handling and braking are superior, and the throttle sensitivity is almost perfect.
There's a HUGE difference between PAS levels 1 & 2, however - I found level 2 FAR too powerful for curvy off-road use. Sondors' difference between levels is much more subtle...
Rad's website once boasted of high-torque motors with metal planetary gears, which I learned on EBR were made by Hengtai. Is that why I didn't get the oil for lubing it after a year's use as shown in their "Owner Support & Best Practices?" The page still shows the Hengtai (pic below) - my Bafang definitely has no oil plug!
Freakyguy666 said this new Bafang has metal gears, but I guess we can't do maintenance on it... plus it says 500W on the Bafang - Rad still claims 750W but I guess that's "peak." Whatever, it's powerful enough for my 50+ needs, but still requires a good workout on my favorite trails.
