    UC Pro Bafang UART motor failure

    When replacing the controller you do need to calibrate it with the proper display. Instructions on YT.

    Show us pictures of where you ride your ebikes!

    No worries. I rode those trails for more years on a bike than an eBike and a good share of those also with a single speed, well technically it was a dingle speed as I had a Schlumpf Speed drive on that bike. There is a network of paved paths in there as well that are fun to ride with little...

    Show us pictures of where you ride your ebikes!

    One of my all time favorite trail systems to ride is located at FT. Stevens Stater Park in Hammond, OR. When I first started riding here 40yrs. ago horses were on them and helped to keep them trodden. Sand base so they would chew up the slopes but not alot of elevation that close to sea level...

    It’s official: E-bikes are actually bikes, not ‘motor vehicles,’ according to new EU rules

    Years ago one of my workers rode his bike to the bar because he planned to get a bit tipsy as was his wont to do. On the way home he got a BUI, Biking nder the Influence, and I can't remember if he had to do a breathalyser but it really messed with us going across the border into Canada to do a...

    UC Pro Bafang UART motor failure

    Yeah those three little screws holding on that cover can be a bit of a pain if they are phillips heads. I've seen both phillips head and torx heads used and the latter is the better one and easily sourced at a hardware store to replace the phillips ones. Getting the cover back on can be tricky...

    UC Pro Bafang UART motor failure

    Are you talking about one of the three main fixing bolts that as a nylock nut? Can't imagine how one would snap like that? I have had several M620's apart and although they should be snug, not sure what the actual torque specs are, one would have to be severely over torqued in order to break...

    "Best advice for new ebike riders" from us

    Good advice and also applies to wind direction. Go out into and return with. OP has sound advice for any make or model of eBike and what has held me in good stead for the past 7yrs.. I do admit to over doing it a few times and having a bit of a struggle getting back to home base. While some...

    Friday Funnies

    Being a little older, I am very fortunate to have someone call and check on me every day. He is from India and is very concerned about my car warranty. I choked on a carrot this morning, and all I could think of was, "I'll bet a doughnut wouldn't have done this to me." Nothing spoils a...

    Multitinker Owner First Week Impressions

    Using auto exclusively does not mean that that the motor is not using "turbo", re: the highest watt output when called for. Especially when on hills with two people aboard. No shame in that as that is what e assist is all about. A higher cadence using a lower gear ratio is actually easier on...

    The Most Fun I’ve Had on a Bike This Year: The Specialized Globe Haul ST

    This was my cargo bike back in 2014 pre e. I went all over on it and one time I even towed a culvert up my friends dirt driveway with it. Was completely hand built with a 49cc 4cycle motor with a 5:1 gear box and a 3x8 IGH/Cassette rear hub that gave it high enough gears to get right along...

    SRAM / Brose motor

    I would wait a bit to see if it has any bugs....gives you some time to save upwards of $8k + I guess. I guess I'm old school and just don't see the advantage of "Smart" systems? Cause ultimately it will need some sort of servicing and the more bells and whistles they put on the more likely it...

    Bafang Ultra what’s the difference between G510 and M620

    I may be assuming incorrectly but I wonder if your plastic gear is the same spec as the steel gear. IIRC at the beginning of the Ultra the nylon gear was a problem for those that were trying to get max watts out of them, looking at you Luna, and they replaced it with steel? If so you could...

    UC Pro Bafang UART motor failure

    Sounds to me like that is the culprit. I would skip AE and go with GBK. My dealings with them have been easy, fast and effective at least. A little over $100 to replace isn't bad and like how they provide a how too video also.

    Bafang Ultra what’s the difference between G510 and M620

    Corn head grease is a polyurea based 0 grade grease that liquify's during use which doesn't effect efficiency (as much) and returns to grease when static. My motor becomes quieter as it operates for example. #2 grade lithium greases remain thick while in use which can reduce efficiency...

    Bafang Ultra what’s the difference between G510 and M620

    The M620's I have cracked open direct from the factory have a very little amount of white lithium in them. I remove an replace with a few tablespoons worth of John Deere Corn Head grease and that lubricates and quiets them down nicely. Others have had success with different grease the main thing...

    New, a 70+ cyclist with a Cannondale Topstone Neo SL1

    Wasn't meant as a slight I just think that it is interesting to note the economy of bikes such as yours. Not knowing what the Ah rating of your battery is I would assume that your wh/km use is quite low.

    New, a 70+ cyclist with a Cannondale Topstone Neo SL1

    Just curious if you have tracked your average wh/km and average speed?

    Multiple e-bikes, one battery?

    It is entirely possible you just have to factor in compatible voltage and how they are constructed and cradeled on the bike as well as the +/- connections.

    Brakes ?? what stopping Me? lol pretty lame I know But?

    Alot. I'd go in favor of the Magura 4piston with the 203 rotors. I have a M620 60lb bike and weigh quite a bit less than you and have a 220mm rotor on the front and 200mm on the rear with 4piston calipers. Stopping power on a heavy powerful bike is not a place to skrimp.
