    Yamaha "zero cadence"

    Hi Guys I am thinking about buying a fully mountainbike with yamaha e-bike system. This features a "zero cadence" feature. Last time I rode an E-Mountainbike it was awfull because the bosch system took about half a crank-turn to kick in. Due to this fact, it wasn't possible to pop some wheelies...

    Improving Panasonic mid-drive assistance

    Hey Ykick Thank you for your reply. I think you mean a new, smaller cog on the motor, right? Because on the rear I can simply switch gears - or am I understanding you wrong? Well, I think I'll live with the bike and someday when the batteries are dead or something like that, I'll just get...

    Improving Panasonic mid-drive assistance

    Hello guys I bought a used "flyer ebike" with the 36V Panasonic mid-drive system. The bike is great so far. It is licensed for up to 45 km/h in my country. The problem is that I barely reach 30 km/h, even in the highest assistance mode. So I don't get limited by the 45 km/h limit but by the...

    Problem with Disk position after deepening of the fork

    Hey Guys I opened some other threads here and was nearly already set for a small front hub set for my citybike. (With a "Cute"-Series Motor: Q100). But then I read that it would be nescesary to deepen the dropouts on the front fork. One question: I have disk brakes. If I deepen the dropouts of...

    Ego-kit for the cheap, offroad-capable freewheel chainring

    Hi --freeride-- and thank you Well, it's less about "real power" but more about function and satisfaction. As far as I can see, there is no way to substitute a broken gearing on the Bafang Kit, and on a bike for heavy offroad use I'd expect to be forced to change the bearing every 2 or 3 years...

    Ego-kit for the cheap, offroad-capable freewheel chainring

    Hey Guys I am totally in love with the ego-kit. This is because I like motocrossing, but don't like the idea of driving 4 hours + with my car to motocross 3h and then go back. This is not environment-friendly and also a bit stupid and boring. So I figured out it needed to be an electric bike...

    Advice before getting BBS02, Sustainability of the drive

    Hey Guys First, I wanted to get myself a rear hub for driving my commuter-bike (about 15Km/day in a not-so-hilly area (the one hill is about 40m / 4Km and one of the steepest hills here is about 70m / 500 Meter). I then realized, that the rear hub is too wide (other users here said that I could...

    Rear hub motor, 130mm width, cst and disk

    Hey Guys Okay, it seems like I overrated the flexing part of the frame, but I am really worried when I read "deepening of the dropouts". This would then be a bigger modification. Is it still possible to insert a normal hub afterwards? I would really like to still use my normal bike, because I...

    Rear hub motor, 130mm width, cst and disk

    Hello Guys I am planning to convert my citybike to an ebike, to help me to commute to my workplace and back (7Km one way). First I planned to use the Q100C Cute motor, with casette freewheel, but then I saw, that it's too wide (134mm). (Bending or stretching the frame is no option) Before I...

    BMSBATTERY PROBLEMS???

    Hey Guys I am planning on buying stuff for my first build, especially a hub motor and a battery. There seem to be many different opinions on bmsbattery and the condition of their items after shipping. So very concrete: Did you order lately from bmsbattery? Are the batteries allright or do they...

    Simple, "Dumb" Controller for Hub Motor

    Hi Motomech and thank you for your reply Well, looking at those prices I have to say that I'd be really stupid to build it all myself ;) Just some questions left which I couldn't answer myself: -As I said earlier, I want to use the bike in 2 modes: the lazy mode (throttle control, no...

    Hey Guys This isn't my first post here but I finally want to start building my first EV-Project. I want to start by converting my normal city bike to a pedelec (20 km/h throttle only, 25km/h with pedal assist are allowed in my country). I have to say that I do a lot of electrical engineering...

    Which controller to choose? Ebike, 27 km/h, programmable

    Hi and thank you for your answer But I really start to like the idea of constructing a controller on my own. I could add a bluetooth module to beam statistics to my smartphone, I could implement other features directly into the controller and so on. Does anyone of you know a "dumb" ESC for...

    Which controller to choose? Ebike, 27 km/h, programmable

    Hey Guys Sorry I left out the wheel size, it's 26". I think 25 to 30 km/h is a fine speed for me, I drive normally at 15 to 20 km/h. Aren't there any controllers which are just "stupid ESC", like in the RC edge of electronics? I ask for it because I do alot with electronics for hobby and it...

    Which controller to choose? Ebike, 27 km/h, programmable

    hey guys I finally want to do it and convert my existing bicycle to an e-bike. The goal is to commute to my workplace (6 Km one way, downhill on the way there, uphill on the way back). In my country it is legal for an ebike to drive about 25 km/h with pedalling and 20 km/h without pedalling...

    Wheelies with hub Motors

    Hey Guys So if I understand you right, it shouldn't be an all too big problem to pop a wheelie - thats good news! Another situation where it is really handy to be able to lift the front wheel is when a trunk or something is in the way, to lift the front wheel over it! I looked at the BPM...

    Motor for Downhill Bike, Sprocket? How to attach?

    Hey guys I am currently planing on my first electric bike build. I want to build a bike with a mid-drive motor. Building the parts shouldn't be a problem because I have access to a very cool CNC mill;) One big point for me is finding a suitable motor. Of course it can't be to big and heavy, so...

    EBike without lag when accelerating

    Hi Amberwolf Many thanks for your answer. The Cycle Analyst looks very interesting. Maybe you can help me with one more answer: I did not see a possibility to set different speed limits in different modes. SO for example 30 km/h when pedalling, 20km/h when not pedalling (only thottle). Is...

    Hi Guys I want to build an ebike especially for driving in the woods, jumping and a bit of light downhilling. I would like to build it by myself, especially for the following reasons: - I once test drove a haibike XDURO FS RS 27.5...
