You have to pre load the rear brake. Apply the brake by hand, pull the cable tight and tighten down the screw. The rear adjustment screw can be screwed in to relax the preload on the brake. It should drag very slightly. The hand control can be adjusted too, screw it out to tighten the cable sleeve/cable.

[@Peasmouldia]

Spot on. The brake lever should have very little travel before you feel the brake begin to bite.

[@wtcamer]

yeah. I mean he had a mile of slack when he put the brake handle on and he didn't go back and adjust xD. By the way the easiest way to explain how the adjustment nuts on there work is to loosen them both and tighten the one that pushes the cable tighter or looser as desired. You may have to loosen the other nut out of the way a few times or just back it off completely once you understand the direction you are going. Once it's adjusted properly just use the other nut to lock in the setting.

A few ideas. Harbor Freight sells a small angle grinder for $17 that will work way better than a dremel for cutting metal. Lok Tite is your friend, especially for the motor mounts. The weak point of this bike is the foot peg mount--too easy to stand up on the pegs and bend them sidways. Better to mount a pipe sideways across the front of the frame and affix fold up footpegs to it. You might think about adding another support to the motor mount, from the L bracket to the 'floor' but forward of the motor location.

Great built but the 8000w is a bit of clickbait. Your 10s (so 36v) battery will need to be pulling 222a to get 8000w. Thats not happening.

[@DIYesk8Builders]

Very true haha

[@DIYesk8Builders]

Oh no this motor is 8000W, its a massive brushless out runner motor, there is no doubt about that. The issue here is that it's just not being given enough current to output that much power. Right now if it's pulling 50A at 36V it's only doing around 1,800W. If we up to a 14s and get a pack that could do 100A, then we could theoretically get around 5000W. The motor is insanely powerful, just not all being used

[@Randomadventurelife]

10s =36v max and max amps for motor is 110a = 4000 watts = 5.36 horsepower. 🙌🏻😋

I suppose so, but the limiting factor atm is the battery. Looking to get a custom pack made soon, but they are $$$

They are nowhere near 7000 or 8000 watts. 8000 watts will dump you on your ass with that gearing and or do a wheelie to 22mph. At least when they eventually make big electric power they will get that e-acceleration rush we all love so much.

[@pudnbug]

this is very interesting, and very thorough. It appears to be doing an electric minibike coming from an RC background, instead of an electric scooter background. Do you realize how much 7000 watts is? That's about 9 hp! Long ago I rode a minibike powered by a Mcculloch go-kart engine (which probably put out around 9 hp) and it absolutely hauled ass! But to get 7000 watts out of your motor, you would need a 14s battery (about 59 volts) that could put out 120 amps - and that would cost an arm and a leg! This electric thing is very interesting, and I'm sure eventually it will completely supersede gas engines, but at present, the only advantage I can see is that it is non-polluting, and quiet (good for mobility scooters, anyway) You can buy a 50cc pocket bike engine on ebay for a little over $50 that would be easier to install, go faster, and not require an expensive and limited-life battery. Maybe some people like their vehicles quiet, but a minibike? Who cares?

[@JohnResciniti]

Never use a hard metal hammer on threaded rods (your rear axle). Nylon rawhide or scrap of wood over the axle, and then hit the wood. Otherwise you'll have some messed up threads that won't accept the nuts.

So you're taking a 7kw motor(pretty sure APS's 80100 motor is 7kw not 8) and bottlenecking it with an esc capable of around 3kw(maybe higher if sufficient cooling). Seems kinda dumb to me? Edit: My bad it's not an APS motor but it's still 7 kw

[@DIYesk8Builders]

We will slowly upgrade all of the components and also just having such a big motor puts it under a lot less stress. Additionally, finding a sprocket for a 12mm shaft is such much easier

Thats 800 watts not 8,000. Get it straight man. Yea i know the company lied. I just bought a 3 kw motor and it was big and cost like 700$ with controller. No malice intended, Just saying. I was in the business for 8 years so thats how i know.

Nice build! Great idea to electrify a vintage style mini bike! I just built a crazy fast razor e-300 scooter using that same 80-100 motor. Just wanted to share the way I mounted my motor, I think it would work perfect for your application. I used the motor case off a stock cheapo 250 watt motor that comes on almost all the cheap electric scooters. I just hollowed it out, broke off the magnets and welded two flat pieces of metal across the front of the case where the 80-100 motor mount holes go. It’s a super strong and clean way to do it. It also adds the added benefit of having a little extra protection for the outrunner because it adds a ring around the motor. It leaves the perfect gap around the motor so it still cools plenty good. Thanks for the info on your video! I learned that I have more options for decent vescs. I’m running the Flipsky 6.6, so far so good but good to know there are other options if this one bails on me.

[@seanturner4570]

In should be a crime to operate a drill, drilling holes and never usi using lubricant for the drill bits. All you're doing is wearing out your drill faster, dulling your drill bits. Makes you work harder, bottom line is it cost money in time

you should use a plastic or copper hammer for hitting the axel , or put the nut on first , or you risk damaging the threads

[@jayeomans]

The link shows your motor produces 17Nm of torque. I use a Bafang BBSHD for my ebike, which can produce 160Nm and 1500W peak when used on 14S, pulling 30A from the batteries (modest for 14S3P or 4P packs using 18650 cells, if each cell is rated at 10-15A). Even the Bafang 250W produces 80Nm. The motor you've got there is for something with little wheels, like a skateboard, so the low torque is mitigated by small wheels (AKA low gearing) and the high wheel speed produced by the high kW output gives you your speed. 17Nm with that wheel/tyre combo is painful and the motor is going to pull huge amps and still not really be any more powerful, unless you can gear it right down to multiply your torque. You don't see 40 ton trucks with 2000hp engines and 300Nm of torque, you see them with 300hp and 2000Nm of torque, to move the load. Point is, 'power' is not always the amount of kW your motor can output, same as HP figures for cars mean nothing if they aren't match by a decent torque figure - that tyre shredding off the line isn't HP, it's torque.. You might be surprised what a 1kW motor can do putting out 150Nm of torque.. Hope you can make it work and enjoy it - you're right, electric is the future..

you can tighten the cable buy pushing the drum break leaver in a bit and retightening it on to the cable or you can slacken the right nut till its all around half way or 75% of the shaft pull the cable back and tighten the left nut if its too tight just slacken the left nut off and tighten the right nut up

U got a motor who supports 8000w it's alright, but the torque aint it, even with a 12s u can't reach the 8000w with this low voltage or u need a lot of P and the controller cant drag more than 100amp continously, i would recommend to go with a hub motor for ebike or scooter and a foc ebike controller that can handle 60-100v there is some with foc too, but after all it's a good job and video but way too expensive for the performance who not here.

[@DIYesk8Builders]

[@emperial4540]

Did you know these are very common in Singapore

[@kmemz]

I'm a bit late to the punch on this, but here's hlw you adjust the brakes, this goes for all types of line brakes, drum, linear pull, or disc: Cable tension. That's it, no frills, no nuance. The lever pulls the cable, then the cable pulls the mechanism, the mechanism pushes the pad to the brake surface. Even the adjustment system that confused you guys so much, is just another part of that; the adjustment just pushes the cable sleeving back, forcing the internal cable to take a longer path (thus increasing tension). You start by getting a feel for how much play the lever that it pulls has, then you pull the lever to the point where it's close to braking, but not. Then you thread the cable in, and pull it taut, tightening it down in that position. The brakes should work pretty much immediately, but they might be either a bit loose, or a bit tight, so use the adjustment screws as necessary to tune it. Not only is the screw at the end for adjustment, but the slotted screw/nut pair right on the lever are also for adjustment; the screw itself for tension, and the nut to screw into the base of the lever to provide cross-thread torque to hold it. As you keep riding, you might find that you have to readjust these occasionally as the brake pads wear down, that is normal. That is everything you need to know to be able to tune your brakes, applying those tips should solve your issues figuring it out. As for the eBike side of things, it definitely works, but it's very jank. Maybe consider buying a high power front hub motor, and get it to a bike shop to get a good fat tire rim spoked onto it and trued. Not only will that give better results and speed than the skateboard motor, but it will save you a ton of space in the frame to overbuild a battery, and you can probably fit a disc brake onto the hub in place of the drum, which gives you both the brake cooling advantage, and the advantage to apply visual learning onto your brake tuning, by being able to look down the side and seeing how twisting the mechanism squeezes the pad into the brake, then the brake into the other pad. Though, it'll be a jank installation getting the caliper into position for sure. Worth considering though.

Yes, you could spend thousands of dollars on an eBike kzbin.infoUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ and get something much higher quality. However, if you're looking for a basic model to try out eBiking this is a great choice. The assembly is easy as far as bikes go (took about an hour for me to do, I'm not an expert). All tools needed are included. I added the plastic mud guards you see and a more comfortable seat. The other reviews are correct that you're probably going to want a better seat (Giddy Up! Bike Seat is what I got - super comfortable). The battery easily handles a 2-4 hour ride if you add some of your own pedal power. I haven't even gotten it up to top speed yet - it is very fast. Components are not top of the line, but decent for the price and work just fine. It works great on dirt roads and singletrack and pavement although too heavy to do tricks or any serious technical mountain biking. I'm looking forward to using it a lot over the summer. Tons of fun!

You sure the motor's 8000W? :/

[@DIYesk8Builders]

its 7000

[@jesperhansen7224]

7000W ebike? Not really. Did you forget to do the calculations on your 36V battery, your motor and the continuous current (80A) of the ESC? Let me do it for you: First, let's check what max current the motor would use at 36V. Motor is 7kW, max current 148A, that is then at a voltage of 48V. So, at 36V the motor max amp draw would be 110A. So far so good. More than the controller can deliver, which is 80A. So, with 36V, 80A, your max power is 2.9kW. If you peak the controller (150A), you'll be able to reach 5.4kW for short bursts. So, what you have is not a 7000W insane e-bike, but a 2.9kW rather modest e-bike. Undoubtedly fun, but when I look at your video, when you drive, it doesn't even look anywhere close to a 3kW bike. My mountain bike with a 3kW hub-motor, easily hits 70 km/h (44 mph) Maybe you were just VERY conservative on the throttle. On the other hand, a quick calculation on your 130KV motor, flat out with 36V, 11/60 sprocket, give you a max speed of about 23 km/h (14 mph). (21 km/h, 13 mph if your rear sprocket is 72 teeth). But you should have some nice rear wheel torque, about 70Nm or so. That said, keep on building, get a bigger controller that can handle 150A+ (for instance a VESC 75/300) and step battery up to 48V, that should be more fun. And make sure the C-rating of your battery is high enough. I'm not sure the one you have can really handle the 8-10C required.

[@DIYesk8Builders]

You are almost all the way right. Yes the battery was the bottleneck for the build but the motor is 7000w which is what we put in the title. And that was just our part 1 video and we are trying to get our part 2 video out within the month. For that video we will get a bigger battery and bigger esc. But for the part 1 video the top speed was 23 mph and it will be faster for the next video.

That's a lot for a frame that runs on such a simple turning concept. But the concept of being low to the ground is kind of cool I think. One thing I don't like when riding on ice in the winter is being so high up because it can really hurt when you fall. The design of this type of bike also makes it easy to repair yourself and things on this, like wheels will last much longer than bike wheels.

[@kstorm889]

I have a very similar motor in my E-foil from Alien power system in 80kv

[@reichenschaller365]

Is anyone else going to mention that there is no way in hell that the motor is 7kw? The only possible way for that to be 7000 would be if it was somehow an ac motor. (Even then that's a stretch) If it was ac then there would have to be an inverter and I don't see one anywhere on there. Also, if that was a 7kw motor then that bike would have roughly 9.5 hp and more power than you would be able to handle.

[@chance1138]

I thought it sounded crazy too. I checked the company's website though, and sure enough those are the specs listed. 17Nm max torque as well. Assuming the company is accurate with their listing, he has it listed correctly in the video.

[@reichenschaller365]

@@chance1138 It has very little torque, hence why it was such a high kW rating.(Understanding horsepower and torque and watts is weird) So they probably dropped the torque to get the wattage number. Also, it most likely has a very weak duty cycle since skateboards are only ridden for a little bit before cooling down. Still, I don't know why the company would shoot for an arbitrary 7000-watt rating.

Quick tip for getting the mount holes marked - rub a tiny bit of grease on your finger then use it to get the front of the motor dirty (not a lot). Then after you wash your hands, rub a blank sheet of paper over the front of the motor (with a hole for the shaft, naturally). Presto, the grease makes a template on the paper that you can use on your brackets. I've seen that trick used countless times on videos of people building frames for vehicles so they could fit all sorts of motors, both electric and petrol/gasoline. Works a treat. Not sure why the manual/cable brake system is giving you trouble - from what I saw you seemed to be doing the cables correctly. But I'm used to mountain bikes with V brakes, not drum. So I could be missing something. It's much the same as the clutch on those little 50cc engines for bikes that were popular here in Australia until they were reclassified as motorcycles and needed license & rego (but they won't pass inspection - cheaters way to ban a fun hobby and mode of transportation)

The cable adjust and mounting is so wonky and seemingly impossible to adjust properly. Sorry for a much too long post, however am Loving the channel and build!

Lol, true. We are taking it off and just going to keep using the regenerative braking. Hope everyone is going to like the update video we are going to do in the summer with a better battery and esc and more!

@@DIYesk8Builders i cant wait for your update vid! I just fell upon your vid today and im all in on what y'all are doing. Im in early retirement due to disability (i.e. vision loss, MS, and some other nasty health stuff) at the ripe age of 52. However i spent the last 15 years of employment prior to 2018 in the forklift industry as an "electric guy" in other words my primary specialty was electric fork trucks and similar equipment. Ive seen for years what electrons can do with a potential difference at either end of a conductor...And as a minibike enthusiast i feel right at home here on your channel!

[@DIYesk8Builders]

I'm sorry to hear about that. That's great that you are enjoying our content! Hopefully this next video is going to be really great!

[@edwardkipp4911]

@@DIYesk8Builders you should have some sort of mechanical brake for safety, if you get real speed out of it and fry the controller and have a runaway motor, you won't be able to stop

AMUSING but.... I can build a GAS mini bike for 1/4th if the cost and and ride 10 times as long with $2 worth of gas VS 1 full battery charge. I love the idea and I think it's really cool that you built it.

Cool Boys good Job :-) Though $1300 is a bit pricey compared to the $1499 price I paid for my Radrover Step Thru 1 E Bike by Rad Power Bikes.

Bro throttle braking?????

[@g4do]

You ever heard of Stanley Meyer? Or Moses West? I think both of their inventions, if combined, would be an industry KILLER! Self refueling water car ? Worth looking into...

To install breaks, install all the hardware. screw in adjusters on the handle and wheel. now pull the cable tight at the cable lock, tighten the lock. Now unscrew the wheel adjuster (stretching the cable) until you feel drag spinning the wheel. Then screw it back in 2 turns. Now if you need fine-tuning, you can do it with the hand control.

[@mckirkus]

Careful with analog ADC inputs, they can go full throttle if the cable breaks. "A pull-down resistor between ADC and GND should be enough. A value of e.g. 10k should work." I'd also recommend putting a bearing on the other side of that motor shaft and stabilizing it so you don't break the motor. The VESC 6 Firmware and tool were just released, upgrade if you haven't already.

How does it compare to the Super 73?

[@danielauen7790]

My diy electric minibike build started with a broken $70 razor pocket mod. the motor controller was trashed. so I replaced it with a 36v controller and a pair of hoverbaord batteries.

[@hori_ink82]

If you put tape on the otherside of the motor shaft and put a bottle over it you’ll get some old Skool motor bike sounds 😜

[@alphazen3108]

This was great and informative you guys went From eboards to mini bikes awesome.

[@magnuslundgardrasmussen7980]

I really wanna make this but this is way to complicated for me i think it would be easier to make myself a mini bike that runs on gas

[@petarilic6207]

Its good, but ya can do any hill with just 350w motor and controller at the same speed and lower battery consumption. Tried my self 😃👍
