Trailer hitch on a Radrunner

Trailer to your Radrunner?

"If anyone is looking to fit a trailer hitch, this is what I did. Used stepper drill bit to make my hitch plate a bit larger and used Dremel to make a notch for the hex head bolt to fit. Then placed the plate behind the axle nut, replacing the washer with my plate. Also, I found a larger hex head bolt to replace the crappy one that came with the bike since it just stripped as soon as a tried to remove it, so now it’s the same size hex head as the other side." - M. V. Sant

"Pardon the crudeness of this example , hopefully it will help illustrate my idea a little better.

Once the three hole bracket is fabed I would weld the replacement part to outer surface ." - James Mj Buche

"I don't like the idea of a side hitch so I built this. I also found Rustolium paint to match the green"

Ändra från 250W till 750W på EU version

J. Zetterman:

"Ja min är en 250 W EU modell, det står 250W på cykeln. Även i displayen så står det "250 W" när man har på assistans läge 5 trots att det då går mellan 30-34 KM/H efter att ställt om den. Fast det blir såklart olaglig efter inställningen eftersom den ger assistans upp till den farten."

Radrunner, coola cyklar med nästan moppedäck.

Bafang G310 Problem

"We found that the G310 motors, as much as we love them have been one of our highest percentage motor failures of our base that we had to deal with. We've had issues with the magnets coming lose. [inaudible], we've had issues with gears failures. That's obvious by suppling them with more power than they can take. Rolling back the phase limits in the motor controller in any of those systems."

TSDZ2 Info

"No, the controller is just the same and the controller can work for a 24V battery pack up to 52V battery pack. The firmware is also the same and the only thing that changes is the EEPROM values that keeps the settings for that low voltage and max voltage." - Casainho

"I have built a number of these 850c bootloaders over the last few years. Very easy DIY project. The trick is that you must use a USB/TTL adapter with a CP2102 chipset in it. This is required by the APT software which uses a CP210 VCP driver."

"Years of posted experiments by real E-bikers on endless-sphere have produced a commonly held rule-of-thumb to avoid heating your E-bike motor to above 95C (200F)."

"When future bike in Italy and another ebike company in Korea started selling a 48v 500w Tongsheng motor last year I contacted a guy I know at Tongsheng Bicycle. He confirmed that it is the exact same motor as the TSDZ2 but with different firmware. He said the firmware upgrade can only be done at the factory and that he could provide me with motors with that firmware - just need to order a boatload of them. He said he doesn't recommend it because it pushes the motor past its 350 watt design. The good news is they are working on a new 500 watt motor that was supposed to be out last year but it is late being released. He will let me know when it comes out."

Högre volt
"I tried an 39.6v 11s battery on my 36v motor to see if I could increase the rpm of the motor. It was absolutely useful in the sense that I could have assist at a higher cadence. The main issue I have with this motor is that with a 36v 10s battery rpm of the motor is too low to assist me when pedaling fast. It starts to lay off at around 75-80 rpm with the 36v battery. 39.6v lets me pedal all the way up to 90-ish rpm. A subtle, but noticable difference.

The higher voltage produced less motor-noise and a more natural assist. It's more than powerful enough for me even though I regularily haul up to 100 kg of extra stuff on my cargo bike."

About getting Bafang 850C color LCD working with TSDZ2

"1. huge memory space of 512kbytes; 2. internal clock that means I will not need anymore to check the hours on my watch while riding; 3. fast communication from the microcontroller to LCD that should permit fast drawing of real time graphs with data like motor current, motor temperature, etc." - Casainho


https://github.com/OpenSource-EBike-firmware/Color_LCD/wiki/Bafang-color-LCD-850C
Microcontoller: GD32F103RET6

This is a 32 bits ARM Cortex M3 that should be very similar to STM32F103.

GD32F103RET6 main characteristics:

Maximum Speed Up to 108MHz
Flash Memory: 512K
RAM: 64K
Package: LQFP64
