How To: Convert ANY bike into a 72v FAST E-bike! **DIY ELECTRIC HUB MOTOR KIT FITTING GUIDE**

[@davidedgerly]

I just found you and I subbed 10 minutes in... I was looking for a channel that builds e-bikes in detail...

[@73megalith]

One thing to consider...uprate the brakes! The discs are stamped with 'resin pad only' I would bin them and upgrade to decent brake discs and sintered brake pads...better for higher speeds.

[@Dr.GreenThumbz]

Sorry to hear about this,Rest well gabi your pain free now girl. Lost both my dogs years back to cancer then a few years later my dad passed from cancer.swore I'd never get a dog again but love dogs so I had no choice. Love the naughty build geeza

[@TheLionsDen72]

Sorry for your loss. We just recently lost our g.shepperd Snow. Hits harder than most may think. For the rotor bolts, since the torque is 6nm, you could shave/grind the heads to flatten them and get a little more clearance. Maybe be an option to try. Thank you for sharine with us.

[@MarvinWestmaas]

I lost Shadow, my previous Am. Bulldog to cancer to, was such a shitty situation really it took the previous owner to come visit and tell me how much weight he lost the last couple of weeks before the doc eventually said the cancer had spread and there was not much he could do ( besides amputating a leg / hip, it was bone cancer ). Took me a couple of months to get my bearing after that, but I'm happy Diesel my current dog came across my path.

@@ianmangham4570 Thanks! It's been over 7 years, that's how long I got Diesel. I hope we got some good times left still.

[@Dmlowe1969]

Sorry for your lost...what's up with all our dogs getting sick from this cancer. Wow I thought it was just me and my cousin but it's becoming more and more of the norm now. Do you think it can be something in the food we feeding our dogs. Or do you think it can be something the Vet mite be shooting our dogs up with. My dog has gotten her yearly shots since she came into this world. She just missed this year. She was suppose to get her shots in March bit that's when I started having my surgeries and I was down. I don't know guys what you all think. So for all your losses. I hate to hear that. I look for my "Remy" to comfort me when I'm home. I'm use to walking in the house and getting mauled with slobbery kisses and hugs. Remy grab my leg and won't let go as to say you not going back out that door mister!😁If something happen to her I don't know what I'm going to do without her she's my baby. 🙏♥️💯

[@Dmlowe1969]

​@@MarvinWestmaas Hope so! As a dog lover and pet owner I know exactly what you was going threw because my dog is going threw it now she has breast cancer. Sorry for your lost again🙏♥️💯

[@MarvinWestmaas]

@@Dmlowe1969 I think cancer is becoming more prevalent because dogs live in the same environment we do. And more and more dogs grow to their old age due to better animal healthcare in general, so I think we're seeing an increasingly elder dog population with it's associated health risks like cancer. I certainly will take a veterinary shots when needed, it's more the pricing which would make me pauze then a lack of trust. Those 1 year shots protect your dog against Parvo, Hepatitis, Distemper, Leptospirosis and Kennelcough. Don't skip on it, or well if you have missed it due to circumstances talk with the vet about if/when to get it anyway later. Vaccinations are a good thing, and certainly don't cause cancer ( or autism... ).

Ive used a hacksaw blade to clean up a thread a few times works pretty good.

[@pablob3128]

The fat tyres E-Bikes are the best to handle high power , well done , beautiful bike , please make more of this you'll sell them all.

[@MarvinWestmaas]

60 amp controller x 84V at full charge ~ 5040 watt ( thank you mr pedantic for noticing my obvious ffin typo mr smartypants ) 60 amp controller x 72V nominal voltage ~ 4320 watt Explains why they market it as 4kw but indeed capable of much more.

[@Calthecool]

How did you get 60 * 84 = 5400? And that’s not even how you calculate the max power, there’s always some voltage drop so the absolute highest voltage you can assume is 80V.

[@MarvinWestmaas]

@@Calthecool It was a spelling mistake, it's obviously 5040. 'There is always voltage drop' yeah but voltage drop isn't universal certainly not when talking about different chemistry and pack configurations. Theoretical max power a better description for you? ps I like you scooters ;)

[@Calthecool]

@@MarvinWestmaas Even if you have a magical battery chemistry that has no voltage drop it will still have voltage drop in the wires. You could call it “theoretical max power”, but I still think that gives it too much credit that it could actually output that amount of power.

[@MarvinWestmaas]

@@Calthecool I just never assume something can reach it's theoretical max, but I still use it even if only for reference. All chemistry has some drop, but it varies in combination with the type of load you're putting on it. Voltage drop along the length of wiring we're using should be negligible unless their using to low high gauge wiring, there are plenty of charts covering this ( but they mostly cover pretty low amps ). ( edit: .. well actually, that chart indicates that voltage drop isn't negligible at all, considering the amount of amps we're pulling. ) That's also why I just use 100% soc voltage and rated nominal amperage this should give a theoretical max nominal wattage. It would peak even higher, but the controller doesn't list max peak so how high who knows. With this I mean that the controller has a nominal amp rating of 60A, that doesn't mean it won't peak higher for short intervals. Anyway, you should obviously know all this already, so I'm not even sure why I'm writing this down ( preaching to the choir we call it ). It's that I think scooters are a death trap waiting to happen, but I really like your Razor build. Should practice your welding a bit more and you'll be able to manufacture things for others ( and have them pay handsomely for it ;) ).

[@Calthecool]

@@MarvinWestmaas thanks for the compliment. I would like to get better at welding, but I don’t really do it enough to get enough practice. I did actually sell the first custom ebike I made and the guy who bought it loves it. I would love to just spend all day building stuff like that but I have to focus on college and family right now so I usually end up rushing builds on the weekend so they sometimes aren’t as good as they could be.

[@andyw3152]

Awesome build. I do want to build a bike with more than 250w, but I'm worried about police clamping down on these.

[@jaykavcher7472]

Honestly even with the qs motor cable with some messing around you can get it fitted with clearance for the cable on most bikes. Don't give up man. And so sorry for Gabi bless x

[@rochekml]

Excellent and honest video as usual 👍. This kit looks a bit too much hassle to fit and work with so ill stick with the 60v. I'll wait for an improved v2.

[@MarvinWestmaas]

30:51 you know what, I would try grinding down those heads. At half their height they should offer enough griping area to be able to mount or dismount the brake disc when needed. If that fails, I would look for m3 bolts with no head but an allen key insert I seen them before and you can get them with very shallow heads, the only question would be if you could torque those to spec.

[@MarvinWestmaas]

40:19 lol... allen key bolts with smaller heads 🤘

[@pukka1]

Love the battery Unboxing tool lol just don't slip with that 😂

[@Verselet_Mantra_MTB]

Cutting a packaging tape with a circular saw is same as shooting a bird with a rocket. LOL. 😂

[@abn0rmal]

The screws being too long is an easy fix. Just chop it down with a tap on the screw, re tap after cutting by tapping it off the screw. Don't know if it's called a tap when making OD threads. Maybe it's called a die. Also, you could grind or lathe to make the hexagonal heads smaller. Cool video. Sorry for your loss.

[@tenncutt]

Yes a die

[@damienakatubbyable]

Hi there, perhaps you can do a experiment where you use an existing mid drive ebike like a haibike x duro for example and add a hub motor to see how that configuration could or couldn't work? I'd be interested in seeing that myself. Thx

[@michaelyounger8767]

Have you thought about countersinking the disc mounting bolt holes to suit Allen head countersunk bolts, which may not protrude as much as the pan or hex head bolts. Worth looking into, hope it helps. EBay has 14mm die nuts for £30 for cleaning up damaged threads, although the thread file worked well.

[@RaysBikes]

Ive got a 48v 1000w kit. Goes 30mph. Very happy with it. With your experience. Do you think a 72v 5000w kit could power a guted motorcycle frame? Ive had a great time making bikes, but ive noticed there's not that big of a jump from a super fast ebike to an electric motorcycle. If you had a light enough, but obviously stronger motorcycle frame. Do you think that would work? Condolences on your pup boss. Good to see you got a new buddy.

You should wear more protection. Would you run as fast as you can (15 - 20 mph) into a wall or throw yourself onto the ground? No, because it would hurt! At 30mph you have a 50-50 chance of life changing injuries. At 60mph you'll be visiting your maker! I came off at just 14mph after hitting oil on the road - it would've been far worse if I hadn't been wearing elbow protectors as these wore through as I slid along. I'm going to upgrade to hard shell pads and hip protection. Great project - keep safe!

I remember that other video :) Isn't it way to generic to say: ow fat tire bike will fit this or that. I mean, hub sizes in fat tyre bikes are not universal, front hub is usually 135mm but for the rear I seen anything between 170mm and 192mm for 26x4 fatbikes. This kit is 1140 euro, granted you do get a nice 20Ah 60v battery with it. Not sure still, I would look at doing it cheaper ordering motor/wheel and ( vesc ) controller straight from Ali. Also, you said around 7 minutes in that it's a 72v battery... not it is not, it's a 60V battery which at 100% soc is 71.4V ( per Kirbebike own website ). A 72v battery at 100% soc would be 84V. I wonder what the max voltage/amps are in the included controller, I'm sure you can get more out of the kit/motor then the 'default settings'.. which is why I been looking into vesc's, makerbase has some nice one's with much higher amp limits then you'll find in your average ebike controller.

[@MarvinWestmaas]

This is the "Kirbebike's 60V 2500W-3000W MTX Rim Ebike Conversion Kit" right? On the website they only offer '71.4V *FULLY CHARGED* 60V LG Lithium Battery' that's why I got a bit confused when you started calling it a 72V battery. edit: nvm, you're using the 72v High Power kit... 2200 euro's... stupid me ;)
