Thanks for the pictures. Interesting life. If you want to save a few pounds, a SS wire rope sling weighs half of what a chain does. https://www.mcmaster.com/8942T14 Mcmaster has 8' and 10' , the latter $80. Try your local industrial supply for wire rope slings with crimped end. Any port city...

Welcome to the site. Interesting profession, archeologist tour guide. I concur on the speed, outrunning a pit bull dog beats spraying it with pepper every time. I dangle sabre spray from the handlebar with a kale or broccoli tie. Always ready. Sometimes dog packs surround me. Good luck on...

I laced a shimano 7000 8 speed IGH into a wheel, but never managed to get the shift ring connected to a shift cable. Universalcycles sells a small parts kit with a bracket, but it ends in a circular clip that fits some sort of bushing. I never was able to buy or make the bushing. I am not...

I used four 5 ohm 225 w resistors connected in series and parallel as a load to test a 48 v battery. 10 amps at 50 volts. My battery had .250" flag terminals on wires. I used 14 ga wire with flag terminals for connections. A parallel voltmeter will detect the garbage. I had one battery drop...

You need to use a meter to measure the battery voltage going into the controller continuously. I have skinned a little insulation off the wires, not at the same point so there would be no short. Then use alligator clips with rubber boots. Could be a connector, could be a battery, could be...

My varia RTL510 is a piece of ****. Warns me about trucks on the interstate 500' to the side through the chain link fence. Warns me of cars 3 lanes to the left of the sidewalk I am on. Warns me of lawnmowers in yards to the side. Warns me of cars approaching a 4 way stop sign from 90 degrees...

I've been warning newbies about cheap imitation steel cables in Rad and other bargain brands for 6 years. It was amazing when I bought a yuba bodaboda in 2017, and did not have to adjust the cables every 2 weeks. I had been riding Diamondback and Pacific, kiddie bikes for people with short...

I ditched the pedal assist, which was always too fast and dangerous for the berms of highways I ride. I use throttle only, on a front hub drive. I get about 5000 miles per 8 speed chain. Mid drives get less. I ride unpowered about 80% of the distance, unless the headwind is >12 mph. Yamaha...

Lithium ion batteries that sit unused for years, lose the mobility of the ions. Green light on the charger indicates the battery is at full charge. But it will not run the motor. A gradual discharge, like the headlight, down to 75% or less, then another recharge, can reactivate a battery. I...

Did you charge the new battery first? I bought 2 garbage batteries, one from Amazon btrbattery one from Ebay sunebike baldwin city warehouse. The 3rd one from lunacycle.com actually worked. Was your vendor as reputable as lunacycle.com? That one cost more than the other two added together...

Hose clamps are not designed for this.

Best luck with the warranty work. I have Tektro cable calipers with about 12000 miles on them. I have had no trouble with failing to close. If cable clamp is not tightened properly, the cable can come loose. Brake pads, the gap should be about 1/64" with the brake handle released. I tighten...

Welcome to the site. Congratulations on using mains power instead of fossil fuel. I have ditched the automobile, mow the yard electrically, but have a diesel tractor for mowing fields. If you don't mow fields, when you sell the price of the bulldozer to scrape the trees off the land and burn...

Pictures are made by devices made in *****. I do not buy things made in *****. I put the screw through a hole drilled in the torque arm, and through holes drilled in the clamp. The clamp wraps the bike frame. No holes are drilled in the bike frame. I put the clamp in the direction so the fold...

I do not know what that is "securing' the torque arm, but it appears to be a flimsy tag. Or perhaps a shredded worm type hose clamp. I use a #10-32 screw through a 1" wide 16 ga steel clamp I cut out of a box fan shell. I cut the steel with a weiss snip. Use kevlar gloves. I wrap the clamp...

I bought a couple of batteries that measured fine until I drew more than 100 watts, when they would drop to 7 volts on 1, 11 volts on the other. Got my money back on the Amazon one. Having a continuous reading on the battery with a separate fast meter was key to spotting the problem. The...

Spoke length is measured from the middle of the end of the bent part, to the end of the spoke. Nipple has to be removed. I use a 6" crescent wrench to adjust spokes. US, spanish or swedish made adjustable wrenches stay straighter than ****ese garbage. If nipple will not move, apply penetrating...

I have never gotten a new motor that matched an old motor, so every time I have to order new spokes from china. Nobody in USA on ebay stocks 2.5 mm spokes. Spoke length calculators are big liars so I just order a little longer or a little shorter than I have already depending on the change in...

Rain in the controller can cause loss of power or failure. Same can happen in the BMS of the battery. Ensure the entry of wires into any such component point down, are shielded from splash, and wires have a drip loop. I realize a factory bike, you have no control over the mounting or wiring...

No 20" wheels for me. Been there, done that, 1957-61. I ride 26"x2.1" tires at 55 psi. Cargo bike, no suspension, no seat post spring, everything feels fine up to 4 hours. My hands & wrists go numb before my back & neck hurt. I second bithigh's experience, 8 mph average is fine. The extra...
