Q100H from topbikekit.com is $96, with $46 shipping via China Post, Probably a sales tax too, making it close to $150USD. Used to pay around $130 USD, so my increase in the States is typical. COntroller, rim, spokes gets me up to $300 USD. Right now, I can get the TSDZ2 for less than that,

I am surprised that you cannot verify the open circuit output voltage on your charger, I suspect it's drifted upward a little. If the BMS is working right, it should limit each of the 13 groups in the battery to a max of 4.2V. If it were me, I would probably get nervous about the 54.8 and look...

I bought the little STM module back in 2019 when I bought the TSDZ2 that was recently installed. I've just wired it up to fit the TSDZ2. I also bought a TSZDB2 from PSWpower because it was marked down to $241 USD. It will be installed on my brother's bike. The TSDZ2 arrived today. Now it's...

In that situation, I often drop to a six speed freewheel, which will gaim 4-5mm, and agree with Neath in that you dom't need all the celarance provided by the torque washer and whatever is on the axle by the freewheel. And if that is a cassette, well then you do what you gotta do, I have little...

Oh my. Oh my. You have to cut those nickel sheets to achieve the same connectivity you were seeing with the discrete strips. The construction method show in your video is also out-of-date. Cells should no longer be placed together like that. Their wrappers are not sufficient for ebike...

Your £ has dropped from #1.35USD to $1.14 this year. I should have come to London last week when it was $1.08USD. I was last there 33 years ago. Really enjoyed it, However, it seems bike parts are getting cheaper for me. I just bought Shimano MT200 hydraulic levers, hose, and calipers front and...

My little Velo-Orange bottle cage clips arrived, so I've put the battery on the lower bar. Riding around today, I find it a pleasure to ride. The motor is silent, and the Raleigh's 27" wheels soak up all the bumps that my 20" folder ebikes transmit. And I'm a slow rider anyway. Have ordered the...

AH ratings for batteries are based on cells, which were tested from 4.2V/cell down to 2.5V/cell, However, for safety. a 48V battery is shut off at 3.0-3.2V/cell by the bike controller and a little lower by the battery BMS, maybe 2.9-3.0V/cell. And voltage sag makes it happen even earlier I put...

I've converted four 20" bikes (three folders and one mini) using Q100H motors and find them pretty good. I've never used one on a 26" wheel, and would probably go with the Q128. On 48V, my 20" folders out-accelerate the TSDZ2 Raleigh and will throttle to a higher speed. My Raleigh was built...

The TSDZ2 is my 10th conversion so I have a good feel for what's fast/slow. As the Raleigh is one of my lighter bikes, I really don't need any assist to go 12 mph in its highest gear, so I can't tell if pedal assist helps much in Eco or Tour mode. My bottle battery can peak at 21 amps on...

My wife used to ride a red Raleigh Drop Bar Mixte in the late 70's. Sadly, we got rid of it, but I came across this blue one in 2021. It's been finally updated with a 500W TSDZ2 that I purchased in 2019. I never installed the Tong Sheng motor, because I heard it was underpowered. and I had...

Thanks for all the info! I powered up my TSDZ2 and rode around a bit, with an RC wattmeter on the battery. In Eco mode. peak current was just 2A. In Tour mode, it was 12A. I was hitting the battery's limit of 21A in Turbo, and then the chain jumped off. I need to do some derailleur tuning...

Yes, I understand the Samsung 21700's are expensive, with the 50S at $10USD and the 50E are $7USD here. But only need 13-14 (if the TSDZ2 will run on 52V).

I've mounted up my 500W 48V TSDZ2 on a light 10 speed bike, but have yet to power it up. I have bigger packs to test it, but want to run on a 26 cell 7AH pack, maybe even a 13 cell (21700) 5AH pack, both in water bottles. What minimum current will I need? Mostly pedal assist at 12-14 mph on...

There are 20 cells in that battery and they only want $40 more for 50E's?. Only a $2 per cell delta, and that is cheap. Some other vendors will charge $6/cell for premium cells. I would expect you couldn't tell by the performance. But if you had 100 of each battery and looked at it 2 years...

I have four bikes powered by Q100H motors, which I bought as bare motors, and then laced up myself. All were ala-carte as I bought the parts separately. I alway check pswpower.com, bsmbattery.com, and topbikekit.com to see which has the best price to me after adding shipping. I prefer the...

With 5AH, you might get 70-90 minutes of riding at 10-12 mph. For £300 , or $375 USD where I am, that's a good price for a motor/wheel/controller if it's well engineered. Adding a useable, but tiny battery is a bonus. I could tap in a aux battery from my collection and ride for miles. I'd buy...

I understand. The motor is oriented with the cable positioned to point downward. I just have no slack in it with that picture, which is with the old fork.

AKM100 328rpm is a good choice. I have one on the rear of my 20" folder, but I also have the Q100H 260 rpm on the front of my minivelo. This is an alloy fork, by the way and it always nagged at me. After a few years, I finally found a steel fork with disk brakes that fit my mini. I moved the...

I believe the Cycle Analyst sends a voltage into the throttle input of your controller. One of the things it can do is read a torque sensor driven off your pedals to do that. Does the Swytch have a throttle? Two suggestions. I believe the motor has a standard 9 pin Bafang cable? You could...
