    Surface604 Yunbike C1

    Have you tried calling the company? If all else fails get a $15 ebike tester and see if it will help diagnose the problem on either controller, motor or throttle. https://www.amazon.com/dp/B0759DMP53/

    Changing freewheel?

    Not your bike but I did the same on a Ride1up from a freewheel Shimano 14-36T to a Dnp 11-30T and I found the 3 extra teeth did not do much. So I then replaced the crank chainring from a 42T to a 48T and that did it for me. Your Yukon should have a 44T up front so it would be better by 2T than...

    Integrated brake light

    My road bike rechargeable lights work in all modes, while they are charging or not charging. I know cause I tested them while charging. There maybe other lights than don't but I've been using 4 of those for 3 years in 4 of our regular bikes and I'm extremely happy with their performance and...

    Integrated brake light

    I also want to add one more thing here. At least of the factory ebike/ebrake tail light I've seen so far (Surface 604 Colt which has a two mode integrated tail light running/ebrake light) as well as the 2019 RadPower ebikes which look to be similar in brightness, as well as the light above that...

    Integrated brake light

    As usual it depends on your controller and every controller is different. Some controllers are made to power a relay and some are made to power a brake light directly. Some controllers don't even have a brake light signal. So the first step is to find a schematic for your specific controller...

    Yamaha PW speed unlockers... SpeedBox2 vs EPlus vs BadAssBox 4 or 3.4

    Just to let everyone know that I took @Nova Haibike advice and went with the PearTune MSO from ebay. Ebay support (questions asked) and shipping were both super fast (from the Czech Republic no less), installation was easy and the fact that you can turn it on and off with the walk button that in...

    Looking for a keyless lock (probably bluetooth)

    BTW, for NON-SMART locks, this is by far the best cheapest U-lock (OnGuard 8000/8001 Brute) for the money, and comes in various sizes. The Kryptonite New York Fahgettaboudit (the king of U-locks) will run you more than twice as much for 1mm thicker shuckle (18mm vs 17mm for the OnGuard). Both...

    Can everyone tell us what is the FULLY CHARGED Voltage with your stock charger of your 36V/48V/52V battery & how many miles you have on it??

    I agree. I think it is time for me to invest on a Cycle Satiator. I've been trying to avoid that due to the price tag but I think it is time to take the plunge. Anyone has a used Satiator they want to part with? :)

    Can everyone tell us what is the FULLY CHARGED Voltage with your stock charger of your 36V/48V/52V battery & how many miles you have on it??

    I hear you... but I've seen others quote, in different ebike boards, fully charged output voltage less than 4.2V per cell. I never seen anyone quote same as or more than 4.2V per cell. So even if it's the 1% accuracy of the voltmeter, I would expect not everyone to be below 4.2V. And that is why...

    Can everyone tell us what is the FULLY CHARGED Voltage with your stock charger of your 36V/48V/52V battery & how many miles you have on it??

    Correct. 36V batteries 10 cell, 48V 13cell, 52V 14cell. But they all should fully charge to 4.2V per cell So you have 10x4.2=42V for 36V battery fully charged, 13x4.2=54.6V for 48V battery fully charged and 14x4.2=58.8V for 52V battery fully charged. So to get the cell voltage you divide the...

    Is there a 3rd party higher capacity battery that will fit the Rook/Colt???

    Thanks for the info Robert. However I'm a bit confused. Looking at the alibaba site https://www.alibaba.com/product-detail/Reention-Dorado-Mini-Pro-Plus-36V_60736873926.html I see this image with dimensions: So given that I measured the Rook battery and it has the same dimensions as the...

    Can everyone tell us what is the FULLY CHARGED Voltage with your stock charger of your 36V/48V/52V battery & how many miles you have on it??

    I'll start: LG cells 48V 10.4Ahr, stock 54.6V charger, FULLY CHARGED VOLTAGE = 54.2V, 134 miles The reason I'm doing this is to see how close to full charge of 4.2V per cell, your batteries get, and if the type of cell has anything to do with it. Mine only gets to 54.2/13 = 4.17V. Thank you.

    Ride1Up E-Bikes

    I use Ibera racks (and bags) on all my bikes (that don't already come with racks - mainly one Haibike which comes with an i-rack) and I have nothing but good things to say about them. Full aluminum construction. No plastic parts. The only thing you will need is a 31.8mm seatpost clamp with rack...

    The best most durable (and affordable) that stays put trunk bag I've had with a clip-on system (that actually stays on the rack no matter what as it has a hard shell bottom that the clip-on system is on) is the Ibera PakRak clip-on bag and carrier rack. Wish Haibike will adapt their racks or at...

    Ride1Up E-Bikes

    I also got a Ride1Up on blackfriday (MTB black version) and I installed an integrated and blinking tail light (comes on when you turn on the head light and is powered by the on board battery), ibera rack, planet bike cascadia fenders, a chainring 48T and a Dnp freewheel 11-30. More info here...

    Integrated brake light

    I did install the light during Xmas as #2 (without getting access to the controller) and wired it to turn on the tail light when the head light comes on. Here are some pictures. The yellow lights are the blinking turn signals. I got a few feet of 18AWG single copper wire from Home Depot and used...

    Do all Haibike ebikes with factory racks come with the irack system or only some of them?

    Bosch Kiox : Obsolete Already?

    I like German engineering but it is typical of them. Sometimes they use something that nobody else uses. I mean I had to look up to see what a USB micro A looks like. o_O
