Thanks, well once most people catch a glimpse of me, they're usually amazed at the sight of what seems to be a dirt bike not making a single sound... when I slow down and they notice the pedals it completely throws them off. If it wasnt for the pedals id probably have a better chance at being harass...

I wanted the same for my EEB, and no fender could satisfy my liking. I decided to just go straight for a full dirt bike body kit. Took some time to fabricate it to fit but it was worth it. It's a yz85 kit which has smaller wheels but wound up working perfectly as the EEB is around the same wheelbase...

This only l...

Got my hands on an Hc 06 and serial usb cable. I sent all the commands to the hc06 from terraterm on windows as the guide says to set the baud rate name etc... everything saved ok. When I connect the hc06 to the sabvoton and run the app, the app says unconnected and does nothing... any help? I assum...

I'm trying to wrap my head about using the HC-06 in place of a dongle. Never touched an arduino before so while it may be a simple concept its all new to me (at the same time learning how much Im missing out on, an arduino can add so many functions in an ebike). My goal is to reprogram my sabvoton s...

Hey alec, i ran into your guide looking for help with my sabvoton, very helpful so far. I have one of these controllers: https://preview.ibb.co/hWwmpm/20171218_110040.jpg The (M) indicates it's a newer model conpatible with Bluetooth, correct? Can you provide any input on how to set one of these up ...

A few whacks with a rubber mallet and I was able to close up the gap on the lip better than expected. Since you don’t know the brand, it is a guess. 16mm 1.5 pitch I believe But you can measure that Grabbed a m16x1.5 nut from home Depot, perfect fit! Trued the rim as best as possible, definitely sti...

Anyone know where I can get an axle nut for this motor? It's missing one and it's not the same as the standard 1000w hub axle nut.

Hugely appreciate everyone's input! took a shot in the dark and ordered some 128mm 10g spokes from Holmes hobbies, as those are for a cromotor in a 19" moped rim. I believe this is the same size as a cromotor and spokes are definitely thicker than the 12g spokes on my 1000w hub so 10g seemed right. ...

Scored this motor and controller combo at what i'd consider a steal for just $75: https://preview.ibb.co/kCCgN6/20171218_185659.jpg It's a 5000w hub motor laced to a 19" motorcycle rim. Very heavy, no distinct markings or model number. Svmc72080 controller https://preview.ibb.co/hWwmpm/20171218_1100...

Video please! this is exactly the type of conversion im dying to do myself one day

Very interested in this kit. How does it fair with recycled cells with not so perfect ends? I have a boatload of cells from echo 58v packs ID want to build a pack with, only thing is most cells have slight bumps from where the old strips of metal were tab welded to.

It's definitely a lot more challenging but I find as long as I keep speed very low it's not hard to "ride" the balance point with barely a pinch of throttle. Since i am constantly standing and shifting my weight to handle the bike, all it takes is a slight lean forward to put the bike down when it's...

Nice build, I like the look of the bike with the dual headlamps. Do you ever get hassled about not having pedals? I've read that NYC is cracking down on ebikes. As long as your riding style isnt borderline causing accidents or actually causes one, NYC cops really dont care much about ebikes the way...

Although the hub is heavy, it being in an 18 inch wheel really takes away a lot of the weight you'd normally feel pedaling a heavy wheel since the wheel is a lot smaller. It also definitely helps a bunch going up hills even though it's already a torque wound motor and gets up hills by itself anyway....

Interesting idea, that thing looks like it can take some serious wattage and not budge one bit! Forgot to mention, entire rear triangle is steel, along with the added triangles. From what I understand I don't really need a torque arm for a shunt modded 500w controller on a steel rear dropout. After ...

Threw an 18 inch hub motor on a 26 inch frame. Before image.jpeg Rode good but the smaller rear wheel reduces crank height, the pedals would grind against the floor during any turn without turning the inner pedal up on a turn. Had some steel triangles from another full suspension mongoose lying arou...

This leads me to believe the purple VK might be it. Right side of resistors leads through some smaller resistors next to it, which eventually go to the VK. Funny turn of events, I have no idea how, but all of a sudden the controller measures full continuity across the positive and negative battery i...

Bump. Any one else have any input keeping the things above in mind? On another note, I hooked up the hub to a controller I know is working, and it seems to be fine for the most part. Except, when you request too much throttle to fast, the hub motor simply stops until you stop on the throttle and try...

I got zero volts checking the resistors with the battery connected. I checked for continuity from the resistors to all wires and none of them beep. Only one point beeps from the left side of the resistors and it is to the right leg of transistor mpsa56, the one under the blue capacitor. (Looking at ...

The orange wire feeds the battery voltage out to the alarm. it's wired directly to where the main battery lead is soldered, so there is no shorting it to the battery wire as it is wired to it already.

I cut most of the wires but I paired them back to their original connections as best as I could. IMG_0319.JPG Here's all the connections coming out the controller. Top ones are obvious ones, battery connector, phases, halls, and throttle. IMG_0320.JPG IMG_0321.JPG Here's the mystery wire bundle. The...
