    Best cell choice for BBSHD fat bike off-road?

    It sounds like you and I may be kindred spirits as far as our riding values/goals! That’s very interesting what you say about the nearly-silent rear hub. At the time I started down the eBike road with my first BBSHD ~ 2016, I dismissed the rear hub idea for two main reasons: everyone I was...

    Best cell choice for BBSHD fat bike off-road?

    So...it’s time to add a 52v battery to the stable, something bridging the gap my current 8Ah ‘pocket rocket’ (Samsung 30Q cells) and 20Ah (Sanyo GA). I’ll be going with one of these options from Bicycle Motor Works: 12Ah (Ampace JP40) 12.5 (Samsung 25R) 12.6 (Molicel P42A) 13.5 (Molicel P45B)...

    Mounting a BBSHD in an Ultra frame?

    "quiet gears"...? Do you mean what is discussed here/sold by GBK? My Ultra/bike was built and shipped to me in May of this year, so I assumed it had these newer/quieter gears. When I had it apart for greasing, I'm pretty sure my third steel gear looked the "New version (B)" showing on GBK...

    Mounting a BBSHD in an Ultra frame?

    Thanks for the feedback; that's what I was suspecting. Ventana sells a BBSHD-ready fat bike frame ("El Gordo") that Cycle Monkey used to create a build very similar to what I'm looking for--sans the step-through frame (although it looks like it has a lower top tube than my existing BBSHD fat...

    Mounting a BBSHD in an Ultra frame?

    Long story short: I searched long and hard for a unicorn of a bike (fat tire, step-through or low stepover frame, belt drive/IGH, Ebike already or Ebike-capable with a motor powerful enough to push ~ 300lbs of rider and gear through mostly off-road terrain) and ended up with a bike that checked...

    No power/current display after Ultra 620 Canbus-UART conversion

    I was debating using that JD Corn Head Grease, but recall reading some comments about it not being the best choice compared to SHC100. At this point I'm less concerned about it being the "best choice" so long as it helps with the noise. But I wonder how much of that noise is really due to the...

    No power/current display after Ultra 620 Canbus-UART conversion

    Thank you il Munduato! And I think you are right about taking some time to get accustomed to the Ultra controller. I think the big question is whether I can live with the noise. After my ride yesterday, I'm not convinced that greasing the Ultra made much of a difference at all. At least as...

    No power/current display after Ultra 620 Canbus-UART conversion

    So I adjusted the settings, and the throttle part of the equation has improved; in fact I need to cut back that throttle power now by ~ 1/3 I think to be where I want it. I'm still--at least for now--not a fan of the torque sensing. How if at all can I adjust my settings to end up with more...

    No power/current display after Ultra 620 Canbus-UART conversion

    Sometimes life conspires to get in the way of riding, but I finally got out on the bike and good news...the power/current appears to be displaying normally. The readings seem higher than I expected, and jump around a fair amount compared to what I'm used to from the BBSHD (perhaps from the...

    Unfortunately, I haven't had a chance to get the bike out for riding/testing. 'Hoping to get out this weekend!

    No power/current display after Ultra 620 Canbus-UART conversion

    I should mention, however, that the BBSHD on my other ebike generated consistent and accurate power data when on the stand. Recently I had a battery that I charged to 95% anticipating a ride the next day, which I was unable to do. I wanted to safely discharge this battery back to a more...

    No power/current display after Ultra 620 Canbus-UART conversion

    I hadn't thought of that...very good point! I'll take it out for a ride and report back.

    No power/current display after Ultra 620 Canbus-UART conversion

    Yes, the bike appears to be running fine--on the stand. I didn't want to actually ride it until I confirmed that I hadn't made some kind of mistake that actual riding would make worse. I've already heard back from Eggrider and sent them some additional information, so I'll update with what I...

    Good idea on contacting Eggrider...I'll do that.

    No power/current display after Ultra 620 Canbus-UART conversion

    Hi smorgasbord, That's what I thought too (pretty straightforward), and I'm thinking that if I made some mistake in my conversion, I'd be seeing other problems than just no Power and Current being displayed. Last night, someone at Green Bike Kit said that I would not be able to get...

    No power/current display after Ultra 620 Canbus-UART conversion

    I just completed switching out the components (controller, torque sensor, speed sensor, and wiring harness, all purchased via GBK) to convert my CANBUS Ultra 510/620 over to UART so I can tune/modify the settings. Everything seems to work OK (although the pedal assist seems slow to engage, but...

    Ebikeschool.com epic China visit

    I really enjoyed this as well, and learned a lot. Videos like this do so much to reinforce the basic idea that whatever you think about a country's governmental policies, people are people. With what we're now seeing with electric cars, China is clearly leading when it comes to e-mobility...

    Like new takeoff KKE suspension fork

    Like new takeoff from a new fat tire MTB ebike I recently purchased. It was installed on that bike for quality control/testing by the manufacturer/seller, but otherwise never ridden. Advertised by the bike seller as 140mm of travel, but I was unable to find a direct match for this model to...

    Unicorn search? Off-road fat step-through + internal hub?

    I just checked out the specs on this Blade 2.0. That checks every box except the step-thru (TT is a bit lower than my current bike, though), and with the 27.5 x 2.6 (with tubeless ready rims, which are nice), that might be a better choice to complement my existing fat bike rather than another...
