    Charging Ebikes on EV Charging stations

    If you read this sites info you will see that isn't going to happen anytime soon, or at least until there is standardization in the eBike charger world: https://fit-ebike.com/en-en/about-us/blog/e-bike-chargers/ However it is possible to find conventional outlets or have them in designated...

    New Chinese Battery Standard

    No real word in that article it the new standard achieves the UL one that is being required in some states here? If not then another hoop to jump through for the suppliers. I happen to know that getting a battery certified is no cheap endeavour.

    Bafang M620 Ultra motor broken? Low torque problem. Best retailer for US?

    I was led to believe that when you swap out controllers you need to "clock" the new one to the motor. Maybe not the right term but it does involve a specialized electronic device that I figured in the end I would have no idea of how to use and I am not shy about mechanics. If you could find...

    Bafang M620 Ultra motor broken? Low torque problem. Best retailer for US?

    https://www.greenbikekit.com/g51-m620-ultra-barebone-motor.html This is what I used when I drowned my original motor. The UART version is preferable because it can be tuned easily via the available programming. IIRC CA eabike only offers the CanBus version. Also you will want the 52v as well...

    Can't find Battery

    The Chinese New Year started today so that will put communication with Herbert at a standstill for a few week. DT is a large supplier of good standing that still will sell an individual battery to anyone.

    Tongsheng slipping

    Could be the sprag clutch? My suggestion would be to just get another motor, which if you are in Asia,should be as cheap as it gets. Install that and continue on and use you tube to help tear down your current motor which should end you up with a spare. 5000k @ 10wh\mile denotes very careful use.

    New 7 speed Middrive motor! Is this the future?

    That Ultima bike looks very sensible and would make a fine bike for alot of urban and commuter types as well as cargo bikes due to the powerful motor. Does lack a way to insert a belt but that could be modified fairly easily via a coupler in the seat/chain stay or going to an elevated stay? Not...

    No charger, no GO? 😥 🚴

    Those bikes are around 10yrs old. Kalkhoff had a presence here in the U.S. in the earlier days of eBikes and had a distributor based in Portland, OR but the brand stopped distribution here years ago. They do still exist in the EU as Derby is still in business and has other brands they sell also...

    Sondors financial troubles

    I was skeptical of Sondors first offering via CSF and somehow he pulled it off. With the beating the bike industry as a whole is experiencing currently the wheat will be separated from the chaff until the next boom arises. Caveat Emptor.

    heavy duty drive train?

    It is too bad that CYC is not developing a final drive option for their system? Anything from the bicycle world will not handle over 2000w reliably. Forget about any type of integrated gear hub at those watts. Only solution, and probably the cheapest, would be to source another front sprocket...

    M620 new quieter gear comparison

    After applying John Deere Cornhead grease to my stock M620 it is virtually silent and see no need for it to be quieter. But glad you have gotten to where you want to be also.

    No Keys: What Are My Options? SOLVED

    There are a finite number of keys that work in those locks. Some ebike shops have a good selection of them you could try. Otherwise take it to a locksmith.

    Cracked frame on 2 yr old Rize City

    Are you certain that the crack is into the tubing, kind of looks like it is just in the paint to me? It is also cracking lower down towards the weld. There really is no good way to repair aluminum tubing other than welding and then heat treating. I don't think hose clamps would fix it if it is...

    Kindernay goes Kaput

    Apparently the German company Kindernay has gone bankrupt. https://www.cyclingabout.com/kindernay-hub-no-longer-they-went-bankrupt/ There was a good amount of interest on here awhile back of those looking to delete their derailleur systems and took the leap of faith to spend $$$$ converting to...

    So far, lots of fun with my Frey Beast.

    IRDM8130SGS Derailleur CS-LG600-11 is now CS-LG700 - ICSLG70011150 Cassette ICNLG500126Q Chain https://archercomponents.com/ Shifter Shimano recommends their shifter but the Archer system due to it's pretty much infinite adjustability works great plus I already had it.

    Bimotal mid drive launch in Berkley

    Got a notice today that Bimotal is introducing a mid drive to the public that has some impressive specs. They also are making batteries available that look to be along the same lines in regards to power output/weight that is more than competitive with main market manufacturers. Early days...
