yes, riding the 48V 18A bmsbattery + GSM motor is similar to riding the BBS02 18A 500W. It feels more torquey and faster than the BBS01 36V 18A that I also tested.Thanks trex, I already have a good 36v 09 battery ( not Bluetooth though)
So it seems like the gsm 36v 18a from woosh is a good deal at 250 quid. Likey less torque than the 48v version you rode I guess ?
So, just for certainty, you over volted the 36v motor using a 48v controller and battery ?yes, riding the 48V 18A bmsbattery + GSM motor is similar to riding the BBS02 18A 500W. It feels more torquey and faster than the BBS01 36V 18A that I also tested.
MAybe a question for woosh but do you recall if the gsm has a similar profile to bbs ? I'm wondering if it has more, less or same chance of hitting the trail on the bottom. I've gone for a 29er conversion to mitigate this issue a littlethe GSM has double stage reduction, same system as BBS01/02.
You can see the middle nylon helical shaft in the picture.
The TCM on the woosh Krieger/Santana CD has a single stage. Double stage reduction allows bigger motor shaft. The motor shaft of the TCM is about 20% smaller (in diameter) than the GSM's and BBS01's. Bigger shaft means less torsional stress, more durable.
inside the GSM: very similar layout compared to the BBS01/02.
