I know parts of the story, Originally championed by Bruce Teakle 10 years ago. If you read his blog both of his first two installs trashed the gears, but he really liked it. A tiny motor with extra low gear for hills? Who wouldn't want one? I did. It was picked up by Luna Cycles. I almost...

I've seen reviews here of off brand bikes. I don't know why EBR mods would worry about them. But your posts, even this one, don't show up,

DId he pick it up to sell/distribute or to ride ? Rad makes a few mid drives, I believe, but the rest of their bikes are rear hubs. A few have torque sensors in the BB. Except for those and the mid drive, an ebike guy can readily replace motors/controllers/displays with something generic...

Our first ebikes came with dolphin case batteries ten years ago. In my opinion, a very rugged case. Bulkier than the current Hailongs but better made. Ebikeling sells a big 36V17.5Ah model. They're a popular kit vendor. I have two of their motors, but never bought their batteries. FTH also...

Knowing the voltage would be nice. It seems your bike has a mid drive motor, Small battery means small rides too, Users want to ride forever. Who wants a 20 mile battery, You can buy bottle batteries like this 36V pswpower model, but it is not much smaller than what you already have, Here's a...

Unless we pack the bikes on the car, we do the same old trail that runs by our house, For a few days every year, it can get brilliant with color. Crossing the mighty Dupage river. We make a 20 mile ride out of it going out and back,

Good topic, but many DIY guys are looking to try increased voltage , Going from 36V up to 48V and even 52V won't hurt most hubmotors. Just make sure the controller can handle the higher voltage and use some restraint. I routinely run my hubmotors on my 36, 48, and 52V packs, accepting that...

I was riding my TsdZ2 yesterday and thinking how nice it was, even if the DM02 is stronger, Dick Tracy approved. In my opinion, Tongsheng sure is stingy about doling out power for old men, but that's why I have OSF. I should mention that electrifybike.com used to sell TSDZ2B's with OSF, but...

I've only had one guy scam me on aliexpress, and it was my fault. I let the dispute window expire while he sent me emails. If the dispute is entered, and you have a good case on video, Aliexpress rules in the buyers favor. I found buying from China quite safe, and economical, but tariffs have...

The Big Apple in a 20" comes in 2.0" and 2.25" widths. We put thousands of miles on them, 2" on my folder and 2.25" on my wife's bike. Low rolling resistance and a great ride. Good Schwalbe puncture protection too.

I've never seen a BBS02 much lower than $400 from China. I recall I paid around $400 in early 2023 at pswpower, shipped out of their US warehouse, but they have no stock in the USA at the moment. I've not bought anything from CHina since August, when the $800 de minimus waiver on tariffs was...

These clamp onto the frame. The axle provides some support. but it's up to the user to make a more permanent install. What I do is cut a slot so the axle can slide in and out, and tie the blue part to the frame, with tapped holes. It's much like making a torque arm. If one could weld, it's...

I've ridden my regular bike 60 miles this year, 100 miles last year, but peaked at 560 miles in 2023. That summer, my wife was injured, so I spent June/July on my regular bike. Normally my wife/I ride about 2400 miles together on ebikes, and I get another 600 solo, To be honest, without...

My DM02 was purchased a year ago, so it has open settings on the T-24 display. I have read that subsequent firmware updates for both display/motor restrict the power. Most of those updates reported bombed out too, if you read the Toseven WIki. https://toseven.miraheze.org/wiki/Main_Page The...

I own four mid drive installs. BBS02B, two TSDZ2, and a DM02. BBS02B is the winner for power and reliability, but I had a setup problem with a 2023 model I did for a friend. Had to use a program cable to set it up like mine. The problem was the factory set speed limits for each assist level...

We do our winter riding with down jackets, but they're still packed away. Been riding around in 52-54F weather with wind breakers and sweat shirts. Cold.

Motor hubs are not standard, but are easy to measure with a $20 digital caliper. I would not trust published ERD's, as you may not have the same exact rim. Easy to measure ERD by putting the parts in the rim as shown above, If you want to be super accurate when setting up the ERD measurement...

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...
