With summer coming I'm concerned about my controller getting hot inside the closed side covers. I decided to take it back apart, and do some ventilating. Without doing any cutting I managed to space out the left side cover. It turned out to be more complicated than I expected because the left side cover holds the right one on. I made them independent of each other, and added some cool acorns.

Have you thought about using computer cpu fans? To run them is like 5-24 vdc .05 ma or possibly an air ram to "shove" air over the components? I have aluminum plates I use as heat sinks on my head. They work awesome.

It's not a bad idea, don't think I hadn't already thought about it.
 
This is a typical commute type of ride on Dallas streets. The kind of ride where you're actually trying to get somewhere and you don't want to take all day trying. In contrast to joy riding where I would ride side streets going a lot slower. When I commute I don't feel comfortable unless I can ride as fast as traffic. This was 49 mph max speed. This is why I claim normie eBikes are dangerous.

How did you work the camera fore and aft? It gave some interesting perspectives.

It's a insta 360 camera. It's always recording in all directions. You have to edit the video later to tell it what direction to look toward. It's kind of confusing and I'm not very good with it. To make matters worse my computer is about 10 generations too old for the program so it's really slow .

This is Bullwinkle, my new build. The donor bike for this project was a Bigniu BGX. It's one of the new generation high speed, low torque eBikes coming out in the last year or so. It wasn't too shabby in stock form, with a claimed 1500w motor, and 40 amp controller, which actually put out over 2000w. I probably could of lived with that but it had one major flaw. It's gear drive hub motor has too much noise coming from its metal gears.. Besides that, it's the best looking eBike I've owned. That makes it a prime candidate for upgrading. This is the most extensive build I've competed so far.
The first thing I did was rebuild the stock 48v battery, turning it into a 72v 20ah pack. I replaced the stock 40 amp controller with a Russian Thermo Nucular F24, adjustable up to 500 amps. I'm running 80 amp. The new motor is a no name ,but probably QS, direct drive 5000w hub motor. My goal was to keep the bike looking as stock, and turn it into a decent street bike capable of keeping up with traffic. I feel like I achieved my goal. Changing the settings is easy, but for now I'm running it at a modest 80 amp, 5000w good for about 50 mph.

I've got a Akez 48 volt with a geared HubMotor and also a Walfisk Warrior Ultra 60 volt Direct Drive HubMotor and
I won't ever own another Geared HubMotor Ebike since they require way too much maintenance. The Akez is a good
Ebike but that company skimped on the forks. The Walfisk has good parts on it except for the Controller, Display and
the Tires. I changed the Tires on the Akez Ebike and it made a world of difference using street tires. None of the new
Ebikes with the knobby tires have that good of a ride even with full-suspension. The fork on the Akez has a nasty
rebound and no adjustment on it. The best speed I could get was, no wind, flat pavement and my weight around 185 lbs.
was just 28 mph with GPS.

The Walfisk is real good with speed and torque even with the Direct Drive 3k HubMotor and the ride could be improved
going to the same street Tires I put on the Akez. I wouldn't trust the FatTires on any of the Ebikes at 50 mph since they
aren't DOT rated. Thanks for displaying a real good mod on that Ebike! I've seen a Blog on YT from a fella that said some
of the earlier models had Direct Drive HubMotors on them and that would be a plus even though startup would be slower.
Thanks...
