I put basically the same motor on a stealth type frame in 2021 (3000w) and I love it. It's my daily driver...weather permitting. The frame is quite heavy of course but I decided to go for something that absolutely wouldn't fatigue over time. I wish more people could experience how much fun these big motors are, thanks for posting.

My build was the 1500-watt kit, on a Shwinn Axum 29' mountain bike. It is great, and still very lightweight. Long ranges with regen with only a 20 Ah battery 60 miles and top speed of 37 mph. It's not high torque but a nice gradual speed build-up. But I still did a steel plate on the drop-out. Super fun commuting all summer.

@@Tomas-ml9nv It's like places banning Juul, they just target the biggest manufacturer representing a market. I've used, tested, opened many lithium battery packs. UPP , in my experience, uses better BMCs, double solder points on cells, and they're internal wiring further showcases their workmanship. Others I've purchased have came w wrong power supply, have shody wiring or BMC failed. And even more I've purchased were actually UPP batteries rebranded. Nonetheless appreciate your reply and input! whatcha using in your builds?

You should be able to swap the 5 speed cassette with an 8 speed one and have it take up the same amount of space. The 8 and 5 speed are the same size, just on the 8 each chainring is closer together. Edit: Also, pretty sure the pedal assist sensor goes on the opposite side of the cranks to the front cassette.

Hi, after watching your video I have decided to build a 5000w myself, and I have a couple questions regarding your build which may help me. 1. The wire coming out of my hub motor (and it looks to be yours), there seems to be 2x plugs that are exactly the same (not the o-ring plugs, the other one), did you just leave one plugged in to none and plug the other one into the controller (I noticed for my controller there is only 1 plug made for this one coming out of the motor) 2. How did you stretch out your battery bag to get rid of lumps and creases and make it look better? 3. How do you pull out the frame to make it (2.5") wider so it can fit? 4. What type and size file did you use for the dropout? And purchased from where? 5. With the blue wire (speed limiter), is there a way for you to choose what the maximum speed is? Just because where I live its 25kmh. Thank you so much, and awesome build!

[@porkercon]

1. I can't remember 2. It was like that from new 3. We only had to pull it out about .5". 4. Flatbastard metal file 5. You can set max speed in the screen.

6:00 If they had stored the velcro straps wrapped around the bag as apposed to around itself it would have been more obvious how they are supposed to be used to secure the bag. The velcro goes on top. at 6:13 you have the bag upside down trying to install the bag as though you'd be wearing it as a fanny pack. The vecro goes from the top, around the bag, under the panier, back up around the bag to the top.

Most times I am at full speed going to work and I only use 2 torque arms with no welded frames for extra strength as its over kill and it's perfectly safe if you know how to handle the immense power it can throw at you.

Why do people use disc brakes on bikes?? Doesnt the v-brake have way more stopping force because it is farthest from the center of the rotation? This is just basic physics. Or do people get discs for vanity?

[@porkercon]

Rim brakes are good yes, discs allow you to have a more predictable braking surface, better modulation, better pad material that you can't use on rim brakes. Way to many reasons to go disc when the only reason to go with rim is the distance from centre of rotation.

Biggest advantage would be if he installed hydraulic brakes. Mech disk brakes are about the same stopping power as good v-brakes, but the disks do work a little better under certain conditions, like if the rim gets wet.

V brakes are fine for pedal bikes. Leverage isn't the only factor to consider. Pad surface area and cooling play as much if not more of a role in terms of stopping power. That's why you don't see v brakes on motorcycles. You won't even see them on manufactured e-bikes unless they're cheap or underpowered. That little thin strip of rubber operated by cables is not sufficient enough when you add a 30lb+ motor serving as an unsprung flywheel outputting 10 times as much power as your legs can do. V brakes are designed for leg power, pedal bike weight and speed. Disc brakes are designed for high speed performance on a motorcycle or downhill racing mtb. A good set of hydraulic disc brakes vs v brakes is like the difference between night and day on an e-bike this size.

i think its better to use a steel frame or much better a custom steel frame...

I agree
