    Tom I just want to thank you and everyone else who helped you sort this brake drumming issue out. I've been putting up with it since 2018. After reading your trials and tribulations I purchased two Magura MDR-P 203mm rotors and some replacement MT5 9C pads. I installed them today and just...

    3W is the limit of what the Bafang can supply (6V x 500mA = 3W). So you should be good with that light set. Interesting to hear trooper5707's trials with the derailleur. I had the same end result but my hanger wasn't bent. My chain was too short and pulled the derailleur into the spokes. All...

    I replied to a message from Ivy about 5 minutes after I got it today (same address) and received the bounce response above. I was only thanking her for her after sales support so nothing urgent but they have had email trouble before. Thought this would be a good way to alert them.

    Frey seem to be having trouble with their email again: The response was: 550 Requested action not taken: mailbox unavailable or not local.

    That’s a good reason. I hadn’t considered it as I rarely have to carry much of a load when riding. A backpack is usually enough for me. For anyone wondering the Mudhugger MTB 27.5 inch mudguards fit on the AM1000 well. I’ll post a photo later. Bit hard to get to my bike for a couple of days.

    Any reason you prefer the hardtail? Having moved from a hardtail to the Frey FS ebike I'll never go back. The ride is so much more comfortable. The loss of efficiency in peddling is easily made up for by the motor.

    Take the nuts off and belt the bolts out with a hammer and a steel rod (I used an old T30 torx screwdriver). Seriously. They aren't threaded, just really tight. By using a rod centred on the bolt you are less likely to roll over the thread with the hammer.

    I had the same trouble with my square taper puller. It worked for my 2008 Giant Alias but not this bike. While the tool threads on to the crank fine, you can see in Ivanovitch's photo above the ISIS has a much larger inner diameter. The centre of the puller just slips right inside with nothing...

    It's not difficult at all. 1) Remove the battery. 2) Remove the three screws holding the plastic cover above the motor. 3) Remove the chain ring and protector. 4) Unbolt the 3 motor mount nuts. 5) Punch out the three mounting bolts, making sure the spider and peddle crank arm are out of the...

    Wow. Yeah mine's no where near that bad. You also have the occasional random ticking noise (not the freewheel) when cruising or pedalling along. Could be something hitting the spokes, a dud ratchet pawl or bearing. Let me know what you find.

    Did you find out what was causing this? I noticed on my ride to work this morning that the rear brake was vibrating quite a bit when braking hard. Not a "bang" noise but disconcerting none the less. I cant see anything obviously wrong with it.

    There are two female half sized spade lugs in the handlebar wiring harness. They switch 6V @ 500mA (3W) using the handlebar controller. If you want to run a light that draws more power than 3W have a read of this: https://endless-sphere.com/forums/viewtopic.php?p=1387972#p1387972

    It's cool. Ivy is sending me one of the longer silver (Al) ones. And the battery is sufficiently Velcro strapped for the interim.

    Have a close look at both sides of your rotor for defects.

    Are these new battery locks available aftermarket? I shook my battery off my bike on my ride to work this morning. Not completely off the bike fortunately. I managed to grab it and shove it back into place rather than letting it fall out.

    It is unwise to raise the start current above 20.

    I haven't noticed this with the torque sensing. I don't use the throttle enough to comment on that. Can post my settings if someone PMs me a link to the software.

    I just wrote this as a reply to a PM and thought I'd post it here as a general review for anyone else interested in this bike: This is my first full suspension bike so I don't have much to compare it to (last one was a BBSO2 Giant Alias hardtail). The first thing I noticed was the weight. This...

    I did not have any luck measuring the ID as my callipers couldn't reach past the clamp section. Your idea of measuring the OD and subtracting the wall thickness is a better idea. I'll have another go tonight. Regarding the light, I used the female connector (from the controller) as it was the...

    I have a set of digital callipers at home. I'll measure the ID of the seat post down tube tonight. Also regarding the light modification, it has an unexpected "feature". The lights activate when the e-brake levers are pulled. Not sure if this is normal behaviour or not but as my rear light is...

    How to run lights that draw more than 500mA @ 6V and have them controlled from the Bafang handlebar control pad. This modification is capable of supplying the full battery voltage at 2.5A. 1) Remove the battery. IMPORTANT! 2) Remove the three screws holding the plastic cover above the motor. 3)...

    This is my first full suspension ebike. It’s like night and day compared to my hardtail. Really smooth ride and the larger wheels make gutters a breeze.

    My Bafang Ultra Mountain Bike! Frey AM1000

    It could have been entering some sort of protection mode because my light draws more than 500mA @6V. It's rated at 5.5W peak, so it was trying to pull nearly an amp. Thanks for the warning about the motor seal. The heat gun I was talking about is for de-soldering SMT components so using a small...
