    I hate 1X drivetrains

    Just perusing some fat bikes and 29er hardtails looking for potential donors and damn if just about all of them are 1x drivetrains that have room for only a tiny 30 something chainring, set into a little pocket in the chainstay that allows no room for anything larger. That simply isn't enough...

    Is there a way to do controlled battery discharge?

    So, it happens once in awhile... I plan to go on a ride and charge my battery 52V EM3EV Super Shark fully, and then something comes up that prevents me from riding. Rather than leave it like that for a week or 2 I'd like to be able to discharge it to an intermediate state. Is there an easy way...

    Skarper disc drive conversion

    I just came across this in my feed whilst reading an article about the current Tour of Britain. This unit replaces the rear disc rotor with one for the drive unit with the standard model working with 160mm rotor setup. The PAS system isn't very clear... the ad copy says it uses a suite of...

    great deal on titanium frames

    Just got this in my inbox... Lynskey is having a 50% off sale on ti frames. Link here is to their gravel offerings that make great all-around gravel, road, touring or e-bikes. I have one of the GR300 that I built up a few years ago and I love it. Pretty much a lifetime piece... very strong...

    EM3EV Smart BMS app for iPhone??

    OK, so I googled this and found one that at least works... Smart BMS Doctor by Powercore... but it provides very limited information. Are there alternatives that show voltage and current cutoff limits and such? I saw a Facebook post by EM3EV from 2018 that said they would have a homegrown...

    VanMoof bankrupt

    And to think I had never heard of VanMoof even though they supposedly had a presence here in the States. https://www.nytimes.com/2023/08/03/business/vanmoof-bankruptcy-ebikes.html

    Charging today - Grin Satiator "volts too high" message??

    I was charging my EM3EV Samsung Q cell 52V super shark for a ride this morning... normal charge, to 58.8V at 4 amps... and sometime after it went into tapering mode at 58.8v and 1.5-2 amps it stopped charging and said "volts too high". I took it off the charger and put it on the bike and it...

    anyone here done CYC X1 Pro Gen 2 to Gen 3 full upgrade?

    I am trying to understand exactly what you get with the "full upgrade" kit. The CYC web site doesn't make this information easy to find. I did find the full upgrade kit there by doing a Google search (can't find it anywhere in CYC site menus??) but the page doesn't say exactly what you get. I...

    Shorten cables on conversion e-bikes

    Has anyone here cut and spliced cables on their e-bike conversions to get rid of the excess? On my mid-drive TSDZ2 and Photon that is mostly needed on the motor controller cable that runs to the handlebars. Of course, that is also the one with the most conductors. Thinking about cutting a...

    Battery storage boxes

    I know, I am sure this has discussed many times but the search function here for any way I can frame it finds far too many unrelated threads to sort through. What are you guys using for safe storage of your super shark packs? I have 2 in an old Sears lowboy steel toolbox for now but it is...

    Pinion - Seen this today at my grocery store

    I have seen this motor/gearbox discussed here but never thought I'd see one locally anytime soon. Looks really nice in person. Love the belt drive. It would be really cool if they would license the mounting to frame builders so we could build our own. I know, never happen...

    Where to put throttle on road bike style drop bars?

    Got a new mid motor coming and I am considering putting it on my gravel bike that has drop bars. I usually like left side thumb throttles on MTB or Hybrid bike type flat bars, but what do folks use and where do you put them on drop bar bikes?

    Mid motor torque ratings

    While I understand that electric motors generate a lot of torque for their weight I wonder by what method and how accurately these mid motor kit and OEM bike mfgs rate these things. You see them rated 50NM, 85NM, even up to 150NM. But these numbers seem unreasonably high. Consider a...

    rear hub motor roadside flat repair

    Thinking of getting my GF an e-bike with a rear hub motor but worried about the rear in case of a flat. Not the flat itself, I well know how to repair or replace tubes and tires. But what about all the tools needed for these hub motor axles? What do you guys carry? Looks like you'd need...

    TTSDZ2B chain line and chainrings

    Got a new TSDZ2, this the B version and the chain line seems just a little worse than the old version on my Cannondale F1000 hardtail w/68mm BB. First, it works OK with the stock TSDZ2B 42t ring. The chain angle is bad on the lowest gears but it stays on... and you don't really need those 2...

    Anyone repaired a broken wire on TSDZ2 torque sense ring?

    Took my motor apart for routine greasing and one of the wires on the TS ring broke off right at the ring. I have a couple of spare rings on order from AliExpress coming on a slow boat from China but would like to make this work in the interim. I'll try scraping away the silicone where the...

    TSDZ2, no drive - "torque fault"

    Well, I busted my TSDZ2, just doing a routine blue gear greasing. I've had this thing apart many times before with no issues but this time the display boots up showing "torque error" on the bottom of the screen and there is no motor drive when pedaling. The motor does run normally in walk mode...

    BBSHD or 02 on bike with internal cable routing?

    Looking to maybe build my brother a BBS based e-bike with a lower end hardtail... most of those I have seen have cables that exit under the BB shell which is where the motor housing would be. How do you guys handle this? Or do we need a different bike?

    seatpost rack for battery

    I have an older Specialized Stumper dual susp converted to CYC X1 Pro ebike and want to try to carry the battery on a seatpost rack. I got one on Amazon with a 20 pound rating which should be fine. Battery weighs about 10 pounds and this will be ridden on the street so the forces should be...

    Expensive USA EV DC fast charging

    I am looking at what my next vehicle might be and a BEV is compelling... and Level 2 home charging would more than fulfill my local driving needs. IIRC fully loaded residential electricity cost here is ~ 15 cents per KWh. The Ford Mustang Mach E with the extended battery I am looking at is...

    Magnetic brake cutoff sensors on road disc brakes?

    Anyone installed an e-bike motor on road bike with disc brakes? If so, how did you mount the magnetic brake cut off sensors?

    CYC X1 Pro Gen 2 chainring attachment

    I am doing some maintenance on my bike and pulled the chainrings off and I can't remember which holes in the freewheel sprag clutch flange the chainring assembly needs to be bolted onto... the threaded ones, or the non-threaded ones? It seems either would work with the backing nuts installed...

    Using a tool battery as a power supply

    Before I got into converting a couple of my bike to e-bikes I had plenty of Li-ion battery tools around and have always loved the versatility and the power you can get from these smallish batteries. We recently got an inflatable kayak and I wanted to be able to inflate it on the beach or near...

    Keirin racing - now I've seen everything

    I just turned to the Olympics on TV and they are showing the women's Keirin races. As a cyclist I am almost sorry to say I had never even heard of this event. I googled it and apparently this has been a sport originating in Japan in 1948. Who knew?? I guess one concession for modern times is...
