    Hiboy S2 Max Mod log

    Well it’s been a while since I’ve posted last. My last project was a razor rx200 that I converted to a brushless/lipo setup. That scooter had great torque but it was small and didn’t have the range I needed. It also ate #25 sprockets like tic tacs. Here’s my new project, the Hiboy s2 Max. I...

    Razor Rx200 commuter/ripper

    Yo! So it's been a while since I've posted or built something, but I'm back. After a lot of working from home, I'm back to commuting to SF, so that means I need a scooter to get from the parking lot to the train and from the train to work, plus ripping around SF on my lunch. I still have the...

    24V Liitokala 26650 build

    So, a while back (on 11/11) I bought some liitokala 26650 cells off of alibaba for a custom battery I wanted to build for my stealth bomber clone. Instead I’m planning on building a battery for my kid’s dirtbike as he always runs out of battery before me and he could use a little more power. I...

    Another Stealth bomber (clone) build

    Hey what’s up guys. It’s been about a year since I’ve posted here during my last build which was a 72v scooter. It’s been running like a champ and is fun and all, but I need something else. Anyway, I need to get to the train station everyday ( 5miles) and I also need to get around SF throughout...

    Frankenstein (Hoverboard + E200) build

    So the other day I was headed to work on my hoverboard from the hardware store in SF and all of a sudden it lost power and threw me off at 10 mph with no warning. I stuck the landing and reset the board, everything seemed fine then it happened again. I'm guessing its voltage sag, but I don't...

    Lyen controller issue

    Hi, I recently bought 2 9 get controllers from Lyen for my dual motor scooter build. I made a Y harness for the throttle that had the polarity of the throttle wires correct but didn't use it because I was hooking up one controller at a time, needless to say I hooked the throttle up with the...

    Hoverboard

    Been meaning to post some pics of my hoverboard (I know its not an actual but that's what they're called). I got it back in October and have been using it to get around SF when I'm not on my scooter. I have to say I didn't think this thing was going to last this long, it's pretty robust. I've...

    250w hub motor scooter mod log

    So a few weeks ago I ordered a scooter off eBay for $560. It looks similar to the ecoreco and vomo scooter just a bit uglier. I bought it to get around San Francisco to and from work. I really wanted a vomo and sent them some emails and never got a response so that scared me a bit. I also didn't...

    mx 400 build log

    So its been a while since I've posted here. It looks like may of you have made some cool stuff. My last build was an E300 with a 6500w turnigy motor. The scooter has been scrapped and the parts have been given to friends/burnt out lol. About 8 months ago I had my first kid and have been busy...

    Motobecane 700ds build

    Hey what's up. It's been a while since I've been on the forum/built anything, so I decided to start a project. I've always wanted a badass mountain bike to thrash on the street and light trails around my house. I've has this motobecane for a few years and really never rode it. The frame is a bit...

    Fake 4110 MOSFETs?

    Hi, I recently acquired 35 MOSFETs that are supposed to be authentic 4110. But,I have heard the rumors about the fake 4110's going around. I would like to sell these FETs, but I don't want to advertise them as authentic if they really aren't. I have a couple pics below, but they're not the...

    Turnigy 80-100b w/halls not working

    Hey Everybody, I bought a turnigy 80-100b motor and added hall sensors to it with no problem. When I run the motor with no load the motor spins up all the way. When I hook the motor to the chain with the wheel off the ground it will spin to 3/4 then cut off. If I try and put full load on the...

    I need your help!!!

    Hey everybody, I was hoping to get some help from some of the members here on ES. I entered the pepsi refresh project to be able to get a 5k grant each month to build ebikes for people. Since everyone here is into ebikes I was hoping to get some support. Not only will you be supportine me, but...

    Controller mod

    Hello all, I have a set up from e-bikekit.com, and want to make some modifications to it. I have already done a shunt mod to it, and am currently running it at 48v. I would like to run it at 60 or even 72v, but I think I will blow some of the circuitry. Can anyone tell me what size caps...

    Hall sensor replacement

    Hey everybody, I'm a noob with a couple questions. I have a 36v 500w bldc hub motor that has been acting up. Basically the motor would make a loud noise when spinning, and would have dead spots that required me to spin the wheel in order for the motor to engage. This led me to believe that the...
