    Yamaha/Haibike battery won’t turn on. BMS dead?

    The 1st and 4th capacity lights flash rapidly when the button is pressed. According to an online manual, that means an unrecoverable error but I don’t see anything that matches the error code of just the 2nd and 4th LEDs being lit during the diagnostic. This happened when I added a discharging...

    It’s very easy. Just remove the bolts on the cover.

    My Bafang Ultra Mountain Bike! Frey AM1000

    Ok, so you've determined that the battery is fine. That's good. Have you unplugged and plugged back in all the connections you can find?

    It could mean you're out of power. The percent remaining is just a reading corresponding to the voltage of the battery, so depending on how it's calibrated, it might not accurately tell you how much power you have remaining. When you apply a load to the battery, it causes the voltage to sag. The...

    Cyclone 650w-1680W up to 60v @2100W without overheating

    It would be much easier on your gears if you ran it at a higher voltage. Yes, the rpm would be higher, and the torque will be lower, so your gears should last longer.

    My Bafang Ultra Mountain Bike! Frey AM1000

    1. I get about 30 mph. 2. Hills are no problem because it has a mid drive that takes advantage of the gears but it's difficult to tell you how fast you'll go because that depends on the load and grade. 3. Derailleur hangers, extra battery. I wouldn't get the shift sensor. I don't like things...

    Bafang M500/M600 thread

    I wonder if it's because of a difference in programming or if Bafang introduced new limits. The battery came with an XT-90 connector, so I made an adapter for the XT-60 connector on the M600. The charging lead on the battery has a XT-60 connector on it. I really like these types of connectors...

    Bafang M500/M600 thread

    These are usually run with 13S packs that most people consider 48V (3.7 x 13 = 48.1V). People have been running 14S or 52V packs on Bafang drives for many, many years, so I see no reason against it. Here's my M600 at 52V. https://www.youtube.com/watch?v=X2IPtda_LFo

    Bafang M500/M600 thread

    Thanks :) Yeah, I thought about even spacing it out further or mounting it on the other side of the spider just to see what speeds a 52T might get me but I don't know if I want to space it out for regular use because of how it might affect the chainline. The reason the 11T is locked out is...

    Here's the 42T on my X1. It is a little too close for comfort, so I'll probably run a 40T. https://www.youtube.com/watch?v=amzIyAd5pn8 You're right that the gearing is probably holding it back, but it might be good that it's geared this way because the point of any bike with a torque sensor is...

    Bafang M500/M600 thread

    My Frey AM1000 (Ultra) weighs 12 lbs more than my Luna Cycle X1 (M600). The X1 definitely feels lighter when lifting it and riding it. When I put a 52V battery in my otherwise stock X1, it went 28 MPH, 3 MPH faster. When I put a 42T chainring on it (definitely not too big for mountain-biking, in...

    My Bafang Ultra Mountain Bike! Frey AM1000

    If you want to haul a heavy load, a Cyclone 3000 is much more powerful. See that trailer train in my profile pic? Cyclone 3000 :) I tried to pull it using a BBSHD with a 30T chainring to a 42T in the cassette, but it would not pull it up the hill that the Cyclone 3000 had no trouble with. You're...

    Wow, that is so kind of you. Thank you Ivy :)

    Just curious. How many miles or kilometers did you get out of the battery?

    Wayne’s Dengfu Carbon Fibre FS 27.5” with Bafang M600 (throttle also)

    Luna Cycle has developed a quiet gear for the M600. Sounds as quiet if not quieter than the BBSHD under load. I ordered one yesterday, so I'll report my findings. https://lunacycle.com/blog/luna-develops-silent-gear-for-the-bafang-m600/ https://www.youtube.com/watch?v=pf78B2HfbXU&feature=emb_logo
