I need some advice please. Ive just upgraded my 5 year olds bike to a better esc, https://endless-sphere.com/forums/viewtopic.php?t=105643 the hobbywing ezrun max 8 capable of 160 amps at 22v, hes definately not going to need this. so i can either put a 6s lipo 5000mah which can handle the...

So the brakes worked an absolute treat. So stoked. Only issue was I made the lever a bit to small, I do get lost in the scale when in fusion360. It does help to have the bars and grip modeled too. But still it came out tiny, much smaller than an AA battery. I had to also redraw the lid and top...

So time to address the elephant in the room. This thing hauls ass and to be a responsible parent and ensure a slight modicum of safety I guess brakes are maybe a good idea. Ok so options were: Mechanical, Pros: They are tried and tested, nobody will question them, they will work with the...

Thanks Mr serious. He's pretty stoked. So next thing is to make some pedals/footpegs. I did make a version a while ago but they weren't right. So out with a piece of card and roughed out a design with a pair of scissors. Chucked that in the scanner and then once again back to fusion360...

To keep it all vaguely respectable I need to keep the battery safe. The way he thrashes the bike already there was no way the battery was going under the sowntube. And it didn't like balancing on top. So i printed some brackets that would fit snug onto the frame and cut a piece of Ali to be a...

So now the thing was going pretty well. He got the hang of the throttle almost immediately. Only one whiskey throttle out the doorway. 😂😂😂 We rode like this for a few days then decided that we need to make it way more efficient. So I managed to ughle in a sheet of skateboard griptape that I cut...

The next step was probably my favorite. Asuch fun as it was controlling his speed from my side he needed a throttle. I'm not sure what the concensis is regarding thumb vs twist. But I decided to go thumb. Back to fusion360 to draw up a housing that will hold a servo tester and let it be driven...

Next step was to connect a RC receiver to test it all worked. I started with a 2s battery to be safe and just edged on the power as he pushed along like normal. The motor spun against the tire and lost slot of power and pushing it down hard just killed any efficiency that the system had. But it...

So first thing to do was to hold the motor and figure how to attach it. I wanted to go belt drive but there was nowhere to get a belt as all the shops are closed. So I decided that friction against the back tire was an easy way to get it going to start with. There was a bit of space below the...

So in South Africa we are having a pretty serious lockdown. You can get shot at and arrested for being outdoors in some areas. So one of the projects was to build an ebike for my 3 year old kid. He has a Cruzee balance bike and a FIT 12" BMX. Size wise he's kinda in-between the two. So parts...
