    Converted a long wheelbase recumbent, a Rans Stratus XP with a slightly used Bafang

    A month or so ago, I picked up a pair of Rans LWB recumbents, one was an LE with the smaller front wheel and the other was an XP with two 26" wheels. My plan was to keep one and sell the other. After riding them both a bit, I decided on keeping the XP. I upgraded the road tires to Big Apple...

    Need some quick help to swap chainring on Tongsheng tsdz2

    Howdy. I've been riding the Greenspeed Magnum a bit and it looked to be topping out at about 12 mph in the highest gear with the default 42 that came with the motor. I looked online and ended up ordering a 48 in the 110 BCD to swap which will give me an extra 2 mph give or take according to...

    Need some feedback on TSZD2 with OSF vs standard OS

    I got the bike put together today and took it for a test ride. What I had left to do was to finish up the battery mount and secure the wiring. I had bought a 3x4x12 piece of aluminum angle and had did some work on it, but was not happy that it would support the battery fully since it was a...

    Need some feedback on TSZD2 with OSF vs standard OS

    Motor and battery came in Friday. I was a bit surprised that it did not have a throttle. Looking online it looks like I got a 6 pin version that does not support the throttle function. I dont think they had one that mentioned a throttle, maybe I just assumed. I'm guessing its possible to...

    Need some feedback on TSZD2 with OSF vs standard OS

    Yeah, that was the only battery that they had with US shipping. Chinese cells but rated for 48v at 12.5a. I shopped around and it looked like comparable everywhere else (Ebay, Amazon) was about 270. Guess we'll see how it works once it all gets here. Not planning on drilling any extra holes...

    Using High Capacity Cordless Tool Batteries in Ebikes

    I've thought about using powertool batteries as well. I have a bunch of Bosch 18v including two 8 amp versions. What I'm not so sure about is how well they would work paired up and how well the battery electronics would play with a load not designed with that battery in mind. From what I...

    Need some feedback on TSZD2 with OSF vs standard OS

    Motor and battery ordered from PSWPower. A bit shy of 500 for both with shipping. Should be here in a few more days. Had to get a special wrench to get the bottom bracket off, but once in hand, it wasn't too bad. Ordered a topeake bar extender for the display and a longer cable for the speed...

    Need some feedback on TSZD2 with OSF vs standard OS

    Thank you both for the quick replies. A few quick questions: Is the V5 software what is shipped from the factory currently? How difficult is it to flash to the OSF version, what type of dongle is needed? I've got a motor and 48v 12.5a battery in the cart from PSW power. Total...

    Need some feedback on TSZD2 with OSF vs standard OS

    Howdy Some background first. I've currently got a Greenspeed Magnum which is a tadpole trike with 20" wheels that I would like to electrify. It's not my first electric bike experience, before this I had a Himiway with a hub motor that was fun to ride but didnt provide that much exercise...
