    Bafang Ultra "Smooth" tune by Mike at Frey

    I initially had trouble getting the right USB driver for the app to work with the cable I had, and some others have reported similar results. You can certainly try, but just be aware there are potentially unique windows drivers that may be required...

    2022 Rize Models - Thoughts/Comments/Experiences From Owners

    Also worth noting that the new battery may need a few full charges to balance the cells and realize peak range. Run it down partially and fully charge it 3 or 4 times before making your final range evaluations.

    2022 Rize Models - Thoughts/Comments/Experiences From Owners

    Well, just my two cents on your concerns: 1. Battery range does not surprise me unfortunately. I'm not sure why Rize went down to a 15ah battery, as that's quite small for the Ultra. It is a battery hog. I have the 19ah battery on last years RX Pro, and in PAS 3 I get as low as 15 miles...

    REI selling Co-Op brand ebikes to REI Co-Op members only during October 2021

    Makes sense. They are a Co-op after all, meaning the members get to make the rules. They've been hit hard by COVID like the others in retail, so prioritizing the members, and encouraging new sign ups are sound strategies for now. It's a tough market for a Co-op that may not have the leverage...

    Rockstar owners

    Looks to me from the pictures like it was inserted during the manufacturing process to maintain the spacing, and then painted in place which has effectively glued it in. Made worse if they used heat curing. If you can confirm that it is just a shipping spacer, cut it in half in the middle and...

    Hydraulic brake not working after pad replacement.

    Don't bleed it without the ability to replace fluid. There is very little in the system. You may just need to clear a bubble. First, raise the reservoir up as high as possible and work the lever to encourage the bubble to migrate back to the reservoir and/or take of the slack you introduced...

    Powershift 2-speed rear hub in a Mid-drive build?

    Anybody familiar with this rear hub? Stumbled across the video recently, and I can't help but think this was make for a pretty slick addition to a smaller mid-drive bike. Might give a unique mix of high-speed performance (particularly when derestricted), and low-range for city/gravel/off-road...

    Where is your Watt Wagons Bike & other things for that matter?!

    I think you are in a very interesting window with WW. They are small enough to be innovating quickly, and producing slick bikes with pretty small overhead. That's a plus and means good value for the products offered, but it also means small companies with few staff cannot handle the...

    SUSPENSION SEATPOST ON MY NCM MOSCOW

    I added them to each of my bikes, and they are good value for the money, But I'd add 2 notes for folks considering them: 1. They are the tallest suspension seatpost option, so you need 4" of available height. If you can't measure very close to 4" between your seat post clamp and the rails on...

    2022 Rize Models - Thoughts/Comments/Experiences From Owners

    There is a pretty low 6v output limit on the Bafang headlight plug, so there are issues with trying to add a really powerful headlight via the stock plug. Since my last gen model has the USB outlet on the battery, I use one of these as a supplement for trail and dark/rainy night riding. The...

    A Teenager Hit Six Cyclists While Trying To Roll Coal And Was Not Arrested

    There may well be an unacceptable reasons the kid was released on scene, but there could be legitimate reasons too. The whole point of arrest for the majority of incidents is to ensure you can determine identity and compel appearance at future court proceedings. If the cop was satisfied that...

    My "misaventure" in e-biking

    A lot of those display-controlled headlights like the ones on the Bafang displays are usually limited to 6V output. If you want to get a serious headlight above that, you'd need to find an appropriate output on the controller (or splice one), and then run a relay circuit to the controller...

    Ultrasonic cleaner?

    I keep a bottle of that WD 40 degreaser, as well as some Dawn Power Spray dish soap in my bike cleaning bucket. The WD-40 gets a brief spray on the drivetrain and greasiest parts at the start of the wash cycle, and the Dawn powerspray does the tires, wheels, and painted surfaces. Super cheap...

    Confortable bike seats

    I bought a DAWAY C40 for my mom's old ebike, and it's decent quality, all metal frame/suspension, and really quite comfy. It's not on par with a truly premium seat, but for casual riders, they will meet the need quite nicely. And with those simple pogo stick seatposts, I'd suggest a little...

    How to build a quality eMTB using Dengfu frame and Bafang motor

    You could probably add the Sondors Rockstar, Biktrix Juggernaut Ultra FS, Frey AM1000 to your list for consideration as reference bikes.

    2021 Rize Models - Shipping Thread

    That is an inherent problem with the stock Bafang programming and always has been. It's pretty jumpy off the line and "could" be a lot smoother across the entire power band. Those of us with the last of the UART Controllers in our Ultras have the ability to change much of the tune and make...
