Replacing front Chainring with a 56 tooth sprocket on Radrunner
Replace front chainring to a bigger on Radrunner
Litepro Road Folding Bike 130BCD 45-58T Chainring Bicycle Chainwheel Bolts CNC
"But the key is to pick an afternarket chainring with 130mm BCD (bolt circle diameter), designed for 3/32" chain. You'll likely also need a new set of "standard length" bolts. since the stock ones on the Runner are longer to accommodate the inner and outer guard rings.
" - K. Hunter

| Photo from K. Hunter |
"Bought an extra set of standard bolts, and kept the Rad bolts together with the rest of the stock components."
"It made a small, but noticeable difference. You'll need a shorter (standard length) bolt set. I added an extra inch of chain, but it wasn't absolutely required. Now that my top speed is "unlocked"....I might go with a 58T." - K. Hunter
 |
| Order some short extra bolts, 8mm or so. Photo K. Hunter |
"Underside of bolt head to end of threads is about 8mm, but a bolt 10mm long should also work, provided the mating "nut" is short enough to not bottom out."
K. Hunter
If you need to replace the chain, this might be a good option:
KMC X8 Chain - 7/8-speed - silver
Dimensions: 1/2" x 3/32" | bolt length 7,30 mm
Material: steel, nickel-plated

Ebike / Elcykel Biltema Yosemite 20" Fat Tire
Made a short video showing some features of the Biltema Yosemite Ebike here in Sweden.
The frame is made in Taiwan, it has 7 speed and a Bafang rear geared hub motor.
New motorcycle tires on Ebike / Rawbike fatbike, Michelin A39 or Michelin City Grip 2
Replace 20x4.0 Kenda tire to motorcycle Michelin A39 tire
Yes, they are more weight, yes they resit puncture on another level.
Moped tire sizes are measured at the inside-diameter of the tire (just like motorcycles), but bicycle tires are measured by the average outside-diameters. A 16" motorbike tyre fits on to a 20" (407mm) bicycle rim.
406mm is the ISO standard and is what you'll likely come across.
If you want a thinner tire, check this out:
shinko SR714 16 x 2.25 moped tire, price $32.99
SR714 slicky tire for 16" wheels
speed rated 93 mph
3lb 9oz

"super easy to put on if you get the tire warmed up (leave it in a car, put it in the sun"

Radrunner motorcycle tire with good result
"currently using shinko 241s 3:00x16, they handle great and not as heavy as regular motorcycle tires so you dont lose much range nor speed" - Jeffrey G.
You can also fit 20x4.0 on Radrunner:

"Bra pris för två nya michelindäck, montering efter alla konstens regler, rengöring av fälgar, byte av bromsbelägg (jag hade med egna nya), 1500 kr för allt. Kvitto med moms.
2 kilo tryck i framdäcket och 2.5 kilo där bak, rullar bra, och tyst." L. Berghe
"I have only driven it 5-6 kilometers since the new tires so I thought I would wait with a deeper analysis. It is quite clear, however, that the Rawbike will be more stable while traveling, no wobble anymore. Before, I experienced that the front tire sometimes tracked and climbed away on bumps, this tire is completely round, and feels "rounder", more stable.
My hope is that these tires will withstand wear much better than the leaf-thin Kenda tires. It rolls better too, even though I had my Kendas pumped hard." - L. Berghe

"Michelin sets the standard for small- to medium-displacement motorcycle tyres. Effective on all the types of roads, the A39 and M39 combine comfort and easy handling. Their durable rubber compound makes them some of the most economical tyres you’ll find."

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

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."

"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

"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
