    CYC PHOTON

    Yes, it is possible to disable the throttle, but IIRC, in the EU and while in "street mode" the throttle is already disabled - "street mode" versus "race mode", the two sets of motor configurations selectable by the display. With the smaller SW102 display (manual), you have a short time limit...

    BBs02 pedal assit level programming

    As in, "Start Password"? If so, no. If you have three dots below the Wheel (size) setting, select those, and then you should see an "Advance setting" row, which when selected should prompt you for the 4-digit password (1919, for example): The "Assist levels" choices are 3, 5, and 9.

    Newb planning a touring build

    When installed, an electric motor system will whisper to your bike, "I'm gonna introduce you to a whole new level of pain!" To the entire drivetrain and wheel in the case of a mid-drive, and for a hub motor mostly to the dropouts and wheel. Especially if you wanna go fast, and not just downhill...

    Newb planning a touring build

    Grin over at Grin (Home page), for ideas on torque-sensing mid-power hubs - via a torque-sensing spindle and a Cycle Analyst display, for example. But, too wide for your bike - dunno how comfortable you'd be widening an AL frame by >10mm. At least you'd know how it can be done. I'd be worried...

    Newb planning a touring build

    I'll ask why you're leaning towards bigger motors on a lightweight "skinny tire road bike", as opposed to the CYC Photon, Toseven DM02, or a mid-power geared & cassette-style hub motor (although finding/fitting a rear hub motor in the narrow-ish O.L.D. rear would need extra consideration, I'd...

    Tongsheng Autopsy - Need Input

    With that amount of riding time (less than 200 miles), and if the brass gear was out of machining tolerance, I'd think the rotor steel gear could chew it up right quick - especially if that sliver @A-DamW pointed out is a broken-off tooth. So, to make it rideable, I'd clean it up thoroughly...

    Tongsheng Autopsy - Need Input

    My guess would be that you have an aftermarket brass reduction gear being chewed upon by the rotor's steel gear, causing metal flake mayhem.

    BBs02 pedal assit level programming

    Most of the 850C display manuals I've come across state the the number of PAS levels is set on the "advanced settings" page, which usually requires a common 4-digit password to enter (1919, for example).

    CYC PHOTON

    @nervagon, you probably already said, but how would the torque multiplier / Motor Assist Factor differ than the three existing Modes & Levels -> Pedal Assist Power / Torque Levels? I haven't fully watched the recent CYC Ride Control video, maybe she talks about it.

    Soldering cradle terminals to controller

    It is likely, and pulling a high current through an environmentally exposed and rather sloppy-fitting connector contact does not help. The female contact spring tension can be tweaked to a degree, but I feel doubling up the otherwise unused contacts is the way to play. That, and checking the...

    Soldering cradle terminals to controller

    I think most of the 48-52V batteries that use these trays use two blades each for the positive and the negative. The older 4-pin blades and corresponding battery contacts weren't known to be that "beefy" when handling high currents - melted connectors occurred. When I had batteries with...

    In a bit of a dilemma...

    Another 20" wheel minivelo (available complete or frameset) is the Itty Bitty from Kyoot Bikes (Austin TX): It's very similar to the Neutrino above, built with 4130 chromoly double-butted steel, and has 100mm QR front/135 adjustable dropout rear spacing. Both the Neutrino and the Itty Bitty...

    Has anyone actually used a 3x3 Nine or Revolute IGH (with or without a mid-motor)?

    @krusty, did you read the posting from @Merlinscave that I linked to, above? Vapor Propulsion Labs LLC. is a Colorado-based U.S. dealer

    Has anyone actually used a 3x3 Nine or Revolute IGH (with or without a mid-motor)?

    Hi @krusty, you might want to read this IGH thread, especially at/near the bottom. P.S. I have a small, personal fleet of BBS-powered IGH bikes, most of which have $100-150 used-off-eBay Shimano Alfine SG-S501 8-speed hubs - all have succeeded. IMO, careful & patient shifting is the key.

    Best IGH for BBSHD powered recumbent trike?

    How does the 3x3 Nine work? Does it have two independent 3-speed clusters in series (as opposed to an N-speed cluster with a separate high/low cluster, as Shimano and Rohloff use)? The fourth speed is 1:1, I believe - is it shell locked? The chain/belt line is a fairly generous 54.7mm - well...

    That's great to hear, @nervagon. I suspect that the firmware update details are on CYC's Facebook area, I don't play there.

    CYC PHOTON

    I've had the same so-so experience with GPS on wooded trails as @raylo32. I use it for course mapping, mostly out in the open, and to calibrate the motor system as best I can. I think Shimano integrates a magnet driven speed sensor into their (probably Centerlock) brake disc rotor. I suspect...

    Apologies - first post and head fried while I fear controller maybe....

    My outsider (not a Tongsheng/Toseven owner) guess would be that the Tongsheng TSDZ2 would work for your situation, as I understand it. But, as @E-HP pointed out, it has some design weaknesses or tradeoffs. Its price point is perhaps its biggest positive, and plenty of happy owners exist.

    Apologies - first post and head fried while I fear controller maybe....

    The Toseven DM02 (and more powerful DM01) is a late arrival to the party, but hopefully, it has an improved design over the earlier Tongsheng TSDZ2 series (both designed by the same engineer, I believe). Hopefully, Lekkie or some other aftermarket chainring vendor will offer a Toseven-compatible...

    Is this tire still good or ready for the trash?

    I unfold them, especially if they're folded/looped incorrectly or have a wire bead.

    Thanks, I'm always worried that my written words don't convey correctly what I intend. You wrote, "kicking in at even 0 PAS setting" - out of the box? None of my BBS motors, when new, operated at PAS 0. There are settings that people have used to calm down the BBS motors - lots of opinions -...

    Apologies - first post and head fried while I fear controller maybe....

    I haven't personally tried it, but I doubt the 36v BBS01 controller will work at 48v, and the components may not be rated for it. I also think the controller's outer case changed slightly over the years, and it might not even fit: Perhaps the motor's cadence (versus torque sensing) behavior...

    Bike Friendly City?

    The rider appeared to have made it approx. 1200 miles, riding an electric bike, and pulling a trailer: The road section, set in a fairly rural area, boasted a significant shoulder width (at least compared to what I'm used to). Poor guy.
