    Bafung Ultra 52v controller on 48v Motor?

    I have / had both batteries when the controler died. The bad battery stopped charging. If you wiggle the charge cord, it will start to charge, but never get over 50%, so I suspect something inside fried? I have the second battery so figured it was a gonner and would just use the other. The...

    Bafung Ultra 52v controller on 48v Motor?

    I have a Frey AM1000 with a Bafung Ultra 48v motor. it came with a 52v 17.5 ah battery. A battery died and the controller threw an error. Not sure they were related, and luckily I had purchased 2 batteries when I bought the bike. I purchased a replacement controller and, like an idiot, thought...

    Question for people smarter than me. I have a Frey AM1000 with the 52v battery pack. The controller died and I ordered another one, but accidentially ordered a 52v controller. The motor is a 48v motor. It seems to work ok, but I emailed Frey to ask if it will cause any damage and they say I need...

    yep, lots of chain drops, unfortunately. Ivy sent me the chain guide when she sent a new rear hub. Blew out the freewheel at the Downiville Downhill. Lots of rides in South Lake Tahoe and northern CA. I have definitely put the bike through its paces. It is a fun powerful bike! Did you tap and...

    Are there supposed to be mounting holes for the chain guide? My motor doesn't seem to have anywhere to mount it.

    Get the light. It's nice to just have it. I like the lyrik/deluxe setup. 52v and extra 52v. Extra hangers for derailleur hangers. I switched to left thumb throttle and shorter cranks 150 mm Delta REF PD11IBT17CA700001541 from Miranda bikes. Makes a huge difference when going up avoiding pedal...

    My Bafang Ultra Mountain Bike! Frey AM1000

    anybody tried running the am1000 as a single speed? It seems to have plenty of torque. My ride buddy never changes the gears and it make me wonder. For those interested, I have had the Frey for several months and quite a few rides. I would suggest ordering an extra few dropouts (as others have...

    My mistake, the pedals are 9/16. There is paint on the threads, so very tight. The 150mm are about 3/4 of an inch shorter

    Miranda Bikes makes a 150 or 155 crank that works. the sku for the 150 is Delta O ISIS with the 16 q-factor offset. REF PD11IBT17CA700001541 https://mirandabikeparts.com/en/products/ebike-parts/delta-0/ Unfortunately, they have 1/2 pedal spindle. most mtb pedals are 9/16 so you either need to...

    There are pics/info on page 26 of this post. I had mine pre-wired from Frey, so the connectors were up near the stem where all the other controller connectors were.

    52v battery performance. A buddy and I both have Frey am1000 with the 52v 17.5ah battery. We rode 28.5 miles in Lake Tahoe (flume trail and rim trail) with 3851 vertical feet of climbing. Moving time of 2 hours and 45 min. We were with a very fit buddy hammering on an Intense, so we were mostly...

    This thumb throttle (left side) is awesome. Plug n play. Much more ergonomic and functional. It is also smaller so controller sits closer to edge. (mount is slim enough to go under controller) here is a link for aliexpress. Under $20 with shipping. 8FUN bbs01/bbs02/bbshd left hand thumb throttle...

    I cross threaded my rear through axle and screwed mine up. 8vy is sending a replacement, and I had an extra derailleur dropout. Hardcore mentioned this rear through axle. Fits perfect! $48

    cool. I had not heard of the vitoria airliner before. interesting. good to hear about the tubeless! Lights are a bit of a gimik. I cut the wire and put on a connector so i can remove it if i want to.

    I could have sworn there used to be a "hide from leader board" option. I cant find it now in my settings. I guess I will stay private so as to not piss off my anti-e-bike buddys.

    Thanks everyone for all the great info here. My buddy and I just received our Frey AM1000s with the 52v 17ah battery. I did tons of online research before I pulled the trigger, so figured I should put in my opinions in hopes of helping others. Besides the Frey AM1000, I also ride a BBSHD 48v on...

    Strava has an ebike setting, and also has an ability to remove yourself from the leaderboard stats so you can stay public but not ruin times. I have been scraping my cranks too. I may have to look into crankarms.

    Buddy and I both ordered and will be shipped today! Went with the AM1000 with the 52v 17.5 ah battery. Upgraded to Lyrik and headlight (so it would be pre-wired and controlled by controller). (we didn't ask for tail light but I guess they come as set). Frey gave us a small discount since we...

    Anybody put aftermarket chain ring on the ultra? Maybe 40 for single-track? There is conflicting info if it is a 5 bolt 110bcd or 130bcd.

    Can someone please post a video of the AM1000 in action. I can't find any YouTube videos of the bike being ridden, only assembled. About to pull the trigger. I do all mountain riding and am hard on my bikes. Want some confirmation it will hold up and rides well. Planning on the lyrik fork...
