No Z916 is the connector on your controller. It is a 9 wire connector with three large visisble pins for the motor coils, plus 6 smaller wires for position sensors and a soeed sensor. The Z916 was picked by RAD because (1) it can handle higher motor currents and (2) no one else uses it. Other...

What happened? Did the axle nuts come loose and spin the motor, twisting the cable and breaking it? In the best of scenarios, you can find another direct drive motor like what you have, or switch to a geared motor like RAS has done in newer City bikes. You work around the possible connector...

This is my cruiser. I got the motor for 45 bucks. Bike is a cheap Kent from Walmart - pure junk. Parked on a frozen lake last February, That front wheel spins like mad on slick stuff, so no, I didn't ride it there, The $250 UPP pack on the downtube is clunky, Less than $500 in the bike...

In the winter, when riding less, the cramps at night were really bad. A hot shower on the legs helped, if I was able to hobble over to the tub. I can't recall them happening at night since last winter, I think spinning the pedals must help keep the legs looser. They used to suddenly occur after...

I believe it's crazier on the West Coast, where the kids can ride all year long and perfect their wheelie skills. Here in Illinois, only the adults are riding now that we have wind chill down in the 40's. My main reference point is my local bike path. The kids used it when school was out, but...

You will need a spoke calculator, and this is the one I've used, I've done over a dozen wheels, https://ebikes.ca/tools/spoke-calc.html The most critical measurement is the effective rim diameter, ERD. For the above calculator, this is measured from the top of the nipple in the rim to its...

Very nice. I looked at the stock guard on the Tracer website. The new one is much better looking! I might have trimmed the end of the chain guard and smoothed it out. Will look just as good. To keep busy tinkering during the winter, they have fake leather hand grips with metal clamping rings...

I'm not familiar with the 860C on TSDZ2B, except on the Bafang BBS02 where it's very good. This would have to be flashed to work specifically with the TSDZ2. Maybe you're looking at a Bafang display manual? I recall the 860 display does show watts. Are you seeing any power readings comparable...

Steel is heavier, but it is stronger. Extra frame strength in a folder is good. Spin the rear wheel backward if you want to check for motor gears. If it has them, they engage and are harder to turn backwards than forwards. I own three folder conversions. All three cost about $250 before...

Never had clips. In the 70's, our bikes used the metal straps on the pedals which took the toe of your shoes. You could always slip your shoes out, but I soon removed them. We had a gal stop behind us six years ago and promptly fall over. I thought we had caused her to crash when we stopped our...

Wow, it is $319 with free shipping. Is it alloy or steel frame (use a magnet)?

There are a wide variety of cells in the market, and if you know what's inside your battery and have a technical bent, the charging and storage temperatures can be looked up. Some cells are rated for storage at -40C and charged at 0C. Most owners will not have that info, so best to use the...

I would expect the Dutch to understand how to do training wheels, as in the second link. As for the Swing Wheels, the install looks it needs a good mechanical guy who can put some tapped holes in the rear frame, if needed.

I've watched our kids, and later their kids, learn with training wheels. They sort of work when you're short and on small wheels, harder to tip over. Nonetheless, that rear wheel will lift off the ground when the kids turn the handlebars. Would get worse with a full size bike. Unless you ride...

The waterways issue extends to beaches on Lake Michigan in Wisconsin. My friend has a home on the water, and it's been long established that he can walk the shoreline as far as he wants in most areas, if he stays on the wet sand, actually along the high water mark. You can also swim and fish...

Sleeves and shims on the hinge posts. You probably already adjusted the latching levers, Worst case, you replace it with a quality steerer, but where to get them. I went thru this four years ago on one of my folders. The replacements sold on amazon, ebay, and aliexpress were just as junky as...

I've had pedal bearings wear out. They sound like that, A loose pedal arm will sometimes pop during a pedal stroke. Middrive motors, because they are applying heavy tension on the chain will amplify noises more. "It feels similar to when a gear's missing a tooth. It happens when the pedals are...

I suppose the problem is finding a smaller 48V motor for the front that can support fat tires? Why give up on 2WD. You can find a smaller motor and lace it into the rim. Yeah, it's not easy, but high school kids can do it in bike shops,

I was in Italy a long time ago. Lots of Vespa like scooters. Props to their e-car movement.

Seems like they copied most of UPP's listings, You even see a small UPP in each one, I would think that either they are UPP, unlikely as UPP has better web designers, or some kind of fake.
