Re: New Bafang Crank-drives

What is the difference between the 250 W BBS01 and the 350 W version? I just got the programming cable working. Wondering if I should try 18 A. ;)

Re: New Bafang Crank-drives

I figured out a way to at least get the front brake to stop the motor using one of the in line sensors. I cut the connector off one of the Bafang brakes and soldered it to this cable sensor at the appropriate length I needed, and installed the sensor below the front cable hanger. It's the only place...

Re: New Bafang Crank-drives

I just mounted the display unit to an old front reflex mount I had in a drawer using a little aluminum bracket I made up real quick. The display now sits right in front of the bars, and it looks much more streamlined. I removed the Garmin-mount. The keypad for the display is secured with a couple of...

Re: New Bafang Crank-drives

I got my BBS-01 yesterday. I quickly installed it on my commuter for testing and made a harness to wire together three different 6 Ah lipo packs. I did not use the brake levers or thumb throttle, as They can't be installed on my bars. Nice build. If you want the motor to cut with braking a HWBS sho...

Re: New Bafang Crank-drives

OK. Well that sure seems to be good use of the power. It also appears to be quite a clime and then to only use 4 AH. I'll be interested to know what the settings are if you ever decide to make/purchase the programming cable to at least see the programming that is there. Being able to make those kin...

Re: New Bafang Crank-drives

It's the 250 W motor and 36 V battery. I have not changed the advanced settings for assist. Advanced setting was set to 3 as default when I looked. I have three assist levels, plus "zero" assist. I have the C961 display unit.

Re: New Bafang Crank-drives

Hehe. That's my bell. The shell opens like wings, which looks pretty hilarious. I went for a little test ride just now. 28,9 km long and 324 m elevation. I used 4.1 Ah of 6 Ah available. I rode at assist level 3 and tried my best to apply as little power as possible myself, and just kept the crank s...

Re: Latest road and single track weapon.

Nice and clean ride. I would definitely put some fatter slicks on the road wheels. Fatter tires have lower rolling resistance and better comfort. Road racers use slim tires for reduced air resistance. I have some 32mm, 38mm, tires and 48mm ries for the bike and will have a bit of a play over the ne...

Re: Comparison between RC and ebike controllers?

Have you guys considered wire length? Battery wire length has to be kept short for an RC controller to last. They don't have large enough capacitors to handle much longer wires than they are delivered with. If the controller is able to limit the current draw (probably a rare feature?) and is install...

Re: Comparison between RC and ebike controllers?

I have a 1/8 scale F-16 on 12S lipos with an electric fan that draws 4 kW at full throttle. The ESC does not sit in the airflow, but inside the fuselage. It doesn't overheat during the three to five minute flights. You can imagine how high the average current draw is to drain a 5 Ah battery in five ...

Re: New Bafang Crank-drives

I have a Bafang BBS01 250 W on the way. I'm just interested in the technology, really and want to test it in case my dad wants me to upgrade his bike later. I haven't decided which bike to try it on though. It's going to be either a Surly Cross Check oamy fatbike I'd have to mill down the fatbike bo...

New mid drive system. BTN TTS-01.

HI. My first post here. Long time unassisted cyclist, and noob with electric bikes (but not electric drive systems in general). I already ordered a Bafang BSS01, and then I found this new cheaper drive system. Has anyone tried the BTN mid drive system? http://www.aliexpress.com/store/product/BTN-new...
