    TSDZ2 750w losing power on hills

    https://endless-sphere.com/sphere/threads/sabvoton-error-02h.113916/ This fellow discovered it means "overcurrent error." In an industrial AC motor, the magnetic fields of the three phases interact to produce torque and back emf, which limits current. If bad contactor points prevent current on...

    TSDZ2 750w losing power on hills

    It seems the motor. I'll bet @harryS could tell you how to check for overheated magnets and windings.

    TSDZ2 750w losing power on hills

    I was thinking of putting one of these on my bike. https://www.amazon.com/bayite-Digital-Current-Voltage-Transformer/dp/B01DDQM6Z4/ I would expect a 2.3 battery volt drop at 15 or 20 amps, depending on how your battery pack is made. If you're not getting much power, I imagine there's a short in...

    TSDZ2 750w losing power on hills

    I say again. Torque comes from amps. The strength of a magnetic field depends on the amps and determines torque. I see he uses a 6% hill as a mathematical example. They're fun with the motor off.

    TSDZ2 750w losing power on hills

    An extra 5 amps will help with torque. Torque comes from amps. The wattage of a motor is a manufacturer's classification. The maximum power delivered to the motor depends on the controller and the battery voltage. I think 24 amps is typical for a bike labeled "750 watts." If a battery with 4...

    TSDZ2 750w losing power on hills

    I've had that happen once when I let the battery get pretty low and again when I let the cells get badly out of balance. The motor didn't get hot. I think OH2 means the motor got too hot, as you observed. AFAIK, a battery problem won't cause that. I believe your kit uses torque sensing. My...

    Need new bike advice

    Gross weight, grade, and tire diameter determine torque need. Suppose you and your bike together weigh 250 pounds. That's 1113 Newtons. The sine of 25 degrees is .42, so you need 1113 x .42 or 467 N. The axle of a 27.5 inch wheel is 35 cm off the ground. 467 x .35 =163.45 Nm. A hub motor would...

    Aah, transporting livestock... One morning in fifth grade a classmate arrived an hour late with an excuse note from his mother saying he'd had to take the cow down the road to be serviced. The teacher asked, "Couldn't your father do that?" "I think the bull does a better job."

    6'5" 220 looking for a bike that will take me up hill on throttle only

    I had a load of logs on my Abound. My gross weight must have been at least 450 pounds. I encountered a 16% grade in tall grass. The ground was soft from rain, greatly increasing rolling resistance. If the 750 watt motor wouldn't do it, I'd be struggling to push the bike. With just a little...

    New tires

    I never heard of rotating tires on a bicycle. In 1970 I found that it was a bad idea on a motorcycle. The classic BMWs had interchangeable wheels, which could run identical tires. Because they were wearing differently, I pulled the axles an swapped the wheels. The first time I leaned to corner...

    New tires

    I must have had about 2800 miles on my Kenda knobbies when I sold the bike. The tread didn't look badly worn except that some green was showing through on the right of the back tire. That's because right turns are tighter than left turns.

    New tires

    I missed the "x" on "Super Moto X" The tread has the same recommendation as the Pickup: 3 bars asphalt, 4 bars gravel, 1 bar dirt. Being 27.5", @DDBB 's tires will carry more weight than my 20" pickups. I guess Aventon used 20" tires to keep the weight of the cargo lower.

    New tires

    I hated the Kenda knobbies that came on my Radrunner. I loved the tires that came on my Abound until I had a puncture at 30 miles. They were only 25 tpi, as well as I could measure. I switched to Schwalbe pickups. I think most bike tires these days have only 1 ply, but these have two plies of 67...

    6'5" 220 looking for a bike that will take me up hill on throttle only

    CC doesn't equate to hp. It's for internal combustion engines. California has a motorized bicycle category that could apply. The limitation is 30 mph. I've read that in America, 750 watts means 750 watts output, on a dynamometer. I tested my Abound on a 6.1% hill and it accelerated to 17.6 mph...

    automatic self-adjusting wire strippers

    We don't seem to be at all observant. If you liked @Mr. Coffee 's, why didn't you buy a little one like his? @fooferdoggie 's is a different tool. It's likely to damage what you grab. Two days ago, @Cliffy recommended twisting an axle with an open-end wrench to get it loose. He said it was...

    automatic self-adjusting wire strippers

    Yes, my control cables were flat like lamp cord. No need for a shield. Like 300 ohm vhf cable but with 3 conductors. RG-6 coax was much better than 300 ohm ribbon cable for UHF. The shielded audio cable would probably have been efficient for carrying line-level stereo over a distance. I wonder...

    automatic self-adjusting wire strippers

    A lighter might help old school strippers. Squeeze the strippers, heat the insulation a little with the lighter, and maybe the strippers can more easily slide the end piece away. With my automatic strippers, I see that the clamp on the side being pulled away has to be within a range. Too loose...

    automatic self-adjusting wire strippers

    Back then I installed rotators at couple of houses because it was the only way to get UHF. A 2 or 4 -bay bowtie antenna on a rotator shaft on a mast on the roof. RG-6 coax because the UHF attenuation was much less than RG-59. A UHF amp on the antenna. The cable would carry DC from the power...

    automatic self-adjusting wire strippers

    A couple of weeks ago I bought these. https://www.amazon.com/dp/B07TS6KCXD I'd always used the kind where you figure out what gauge wire you have, find the notch in the strippers, use one size bigger if the wire is stranded, clamp the wire with the sharp hole, turn the stripper to be sure the...
