Electrically actuated freewheeling clutch on a hub motor. Cogging torque problem solved with zero tradeoff. Electrically actuated freewheeling clutch on a hub motor + one-way freewheeling clutch on the pedals only. Problem solved for hub motor too. Might be a bit mechanically complex and bulky.

use a LUBE on the thick part of the cable/fish tape. that should make it easier to pull.

I just purchased a Phaserunner controller from you. I'm not going to use it on the bike I'm going to talk about right now, but in theory can't I use the phaserunner controller to check the hall sensors? I had to swap motors since the broken bike I just fixed had a motor problem after replacing everything else. The motor will run up and then stop running, then I get error 8 on a display that runs the Bafang protocol. The new motor harness I made can connect right up to the phaserunner, I did it so I could quickly swap out from one to the other when I need to. I have the products I purchased from you set aside since I was going to work on that after my mode of transportation was working and reliable. Since I'm not using that motor now I was planning on fixing it next.

An electric motor can freewheel all day if it's in an open circuit. The drag depends on current. The regen function could be handled by a slightly smarter motor driver that could control the amount of current being allowed to flow back into the battery. I appreciate a good mechanical solution, it's certainly more than I could come up with, I just think more in terms of electronics. I was kind of disappointed that no ebike manufacturer seems to value regen, but they're certainly right that an extra drag force on pedaling would be a nightmare if you ever had to use it. So make a switch lol.

Justin.. I currently have a Maxeon SunPower 170w 29v panel.. I paired it with the GVB-8-LI-58.4V-WP ... i wanted to get the larger Maxeon SunPower 330w panel to increase range.. But was told by Genesun: "Your proposed 330W has a Vmp of 56.9V and a Voc of 65.4V, so it is not compatible.Additionally, if you wired 3x of the Maxeon 100W panels in series, their voltage would be to high as well. What kind of solar controller would be able to handle the SunPower Maxeon 330w panel..? Do i need a controller (as the voltage is rated at 56.4v.. (that will never fully charge to 58.8v..) .. I understand that the BMS on the battery will shut off the charging (like the solar controller) so it won't over charge the battery and cause a fire.. Is there a controller suitable to charge a 52v battery..? that is paired with the 330w panel..?

Let’s go be a lot better than a regular damn brakes trying to get them adjusted just about drives me crazy now I’m scared it’s gonna snow and I ain’t gonna get to ride my bike cause it’s broke down the motor. I’ve only had it for six months the wires is all tore up. I don’t know what to do. I guess. I’ll have to send it to you guys. I’m not very good on the phone. I was diagnosed with C LL about a year and a half ago that keeps my mind off of it. It had a two year warranty, but I don’t think they would even take it back. Plus I lost a receipt.

Possibly. Or the BMS is doing it's job perfectly and you have a cell group that is at a critically low voltage, or perhaps just your on/off switch is broken. Speculating only gets you so far. Instrumentation gets you to the root cause.

By literally doing exactly what is explained in this video, but it's hardly a walk in the park and requires you being pretty committed to learning and understanding all about how ebikes and BLDC motors and motor controllers operate. If you can source a drop in replacement display/controller from Go Trax that of course would be much simpler. Your situation is a sad reality that countless people face from the supply of DTC turn key factory ebikes.

FRONT MOTORS ARE NOT GREAT IN WET
@GrinTechnologies 11 күн бұрын
It depends a lot on the particular bike geometry how the weight is distributed between the two wheels. With a lot of cargo bikes, pedicabs etc. where this would find an application, there is more than enough weight on the front wheel to have plenty of traction even in wet weather. Otherwise on a conventional bike where 80% of the rider weight is on the back wheel, it's both easy and smart to limit the torque and/or acceleration of the front wheel so that it's less likely to skid when throttling in slippery conditions.

I love the clean approach of this business, both in the products and videos. Any updates to solar ebike touring technology?
@HoboGardenerBen 12 күн бұрын
Random idea while watching this. A heavy duty camera mount that attaches to the center of whatever flat platform the panel is attached to. They have that sweet ball joint that allows adjustment into any angle of the half-sphere and lock it right there. Being able to tilt the panel on a trailer in a simple long axis would be helpful but the center pivot would help get max light if on a road going a weird angle from the sun.
@GrinTechnologies 11 күн бұрын
Yes, solar tracking is a big thing for those who want to eek out every available percentage, and it can really help at higher latitudes. Lots of examples of automated tilting devices, kzbin.info/www/bejne/mISwppqaYtx6epI And manual ones: kzbin.info/www/bejne/jp-Qd2B7n8xlj9Usi=8cL7KbYe97-5RAQE&t=170 But the camera gimble mount as a starting point for the hardware is a clever idea as long as it can cope with the wind forces.
@HoboGardenerBen 11 күн бұрын
@GrinTechnologies Cool, I had seen the automated ones that tilt on the long axis, but nothing multidirectional. I'll have to look more deeply into what people have thought of. I don't even know if there is a ball mount that is strong enough for the weight added to the system. I'd keep it manual, not a full-on tech enthusiast, usually like to pare things down to the simplest effective design. Thanks for the reply, be well :)
@HoboGardenerBen 11 күн бұрын
@GrinTechnologies Had another idea watching your manual tilting design. A simple frame of four posts with strong adjustable straps and holes along the length of the supports to be able to move a carabiner up and down for whatever angle you want. Slow and fiddly but simple and effective. Not quite sure how make the supports strong enough without crossbars that would shade the panel. Might only work in a low profile setup, not tall wobbly posts, just a bit of angle adjustment and covered cargo space. Not sure how much adjustment angle you need to gain charging value.

I'm wondering what the disc brake pad wear is like. I'm assuming it's far less ware than traditional disc braking?
@GrinTechnologies 11 күн бұрын
Exactly. Since the disc rotor is spinning was slower, it barely gets remotely warm to the touch and so the pad life should be greatly improved. It's one of the things we hope to properly quantify in a A vs B lab test this winter.

Lovely simple looking set up. I'm running a Norco Bigfoot with a Bafang BBSHD 1,000 W mid drive which is great but certainly hub drives, especially on fat bikes, offer a less complex set up - eg chain alignment, etc. The hub spacers to accommodate diverse axel dimensions/type are great. Nice kit!

I have the All-axle hub mated to the Phaserunner and Superharness. It runs smooth and quiet. The belt drive that I am using actually makes more noise than the motor. Interesting the torque sensing feels great now that I have it hooked up with the Superharness. When I ran it with the CA, it felt a little quick with ramp up causing me to spin out faster. For context, I have this on a 20 inch minivelo travel bike with 72volt molicel battery. I want this motor for my Radwagon 4 as a retrofit.

I also do not like the look of hose clamps, and I'm just using heavy duty zip ties. It hasn't moved at all and works great. I carry extra zip ties jic.
@GrinTechnologies 14 күн бұрын
The forwards torque of the motor pushes the torque arm into the frame, so the straps don't really have to deal with any tensile forces when you motor away. It's only when you are doing regen that the frame clamp is being pulled away and the zip ties are what's holding things snug. 100 Nm translates into about 150 pounds of force at this distance, so as long as your two heavy duty zip ties combined have a pull out strength with safety margin above this you should be fine. If it's dicey, you can always reduce the max regen phase current to like 40 or 50 amps, still decent stopping power but with less stress on the hardware.
@DereckHowerton 14 күн бұрын
@GrinTechnologies thank you! I think I'm using regen with dyol throttle? I'm using it as a break...it's an amazing setup. The ties have handled it though.
