hi all contemplating my second conversion. This is for my trekking /hybrid, a Giant Roam. I want to be able to switch it back to using in fully non-ebike mode quickly and easily so a hub motor is a must. would prefer rear hub for the obvious ride quality reasons. Been out of the scene for a...

hi all been running my TSDZ2 converted dahon folder for 2 years now, 2000 miles commuting, all very reliable. I've serviced and/or changed all the usual wear and tear parts on the bike but not the e-parts. best mid-life upgrade I did on the bike was to go to a narrow-wide chain ring...

thought I'd post some pics and info for those who might be interested. After sitting on almost every ready-made electric folding bike on the market over a period of 6 months, I decided I didn't like any of them - basically all of the frames too small and forcing the upright riding posture...

hi whoosh. thanks. I tried grease but didn't gain much. however I bought some burr and grinding bits for my dremel and slowly shaved tiny bits of the inside of the BB shell away in the central unthreaded section, and was able to get it fitted. and it rocks. reference our previous discussion on...

whiteturbo - interesting you say all that, I've ridden the same two motors as well and reached the opposite conclusion! I've just built TSDZ2 onto my dahon folder. I was previously riding a borrowed whoosh dutch style bike (heavy) with a BBS01. I particularly disliked the lag on power delivery...

finally decided on a tongsheng tsdz2 to convert my dahon. ran into an unexpected issue after removing the bottom bracket. The motor spindle won't push through the hole - it stops once the threads are in, after only a few cm. I've tried moderate percussive force (gentle tap with hammer), don't...

I've had a bafang BBS01 on long term loan, and ridden bosch in shops. No comparison which felt better, but not a fair one either monetarily or in terms of how/where you can get it (needs to be on a new purpose made bike). So I'm trying to decide bafang BBS01 (which I know is a bit clunky) or...

on the folder - the only way it'll fit is with the whole thing rotated so the motor sits in front of the BB not under it, so probably not going to be able to use the chainstay anchor. Keen to see any pics of peoples installs (just the motor bit) if anyone can oblige? I'm just wondering if the...

A few questions to TSDZ2 users. I'm thinking about using this motor on a dahon 20" wheel folding bike. It would have to be fitted with the motor unit rotated forward of the bottom bracket, not under it as per many of the diagrams. there is a picture of a dahon bike with it fitted this way from...

well now I am thinking of going front hub for simplicity. what do people know/think of these ? http://shop.crystalyte-europe.com/product.php?productid=16694&cat=327&page=1 - 74mm so fits right in without messing with the fork dropout - can be run at 36v or 48v for more oomph 48v and 36v...

ta for the help on the TSDZ2 orientation and throttle. On the dahon folders, the seat tube pushing all the way down is part of its stability when floor standing. as it will be in a train carriage for me. so a motor design that stops the seat post going out the bottom isn't going to work for me...

you have caused doubt but I think its a valid doubt... studying the TZD2 install diagram that bracket looks like it clearly attaches to the horizontal between the chainstays. meaning the motor can't be anywhere other than under the axle - thus invalidating it for a folder where the seat post...

I think that will be the key. On a folder, directly underneath the axle is a no go area - the bottom of the seat tube will come out there (seat post usually will come out through it down to the ground to act as a stand ) and/or there is often a stand there welded into the frame to keep the...

ok if you get to the point of having a built bike with one I'd be interested to take a look. thats not what I was aiming at - wouldn't want to press a throttle from a standing start. More about using a throttle to force the motor to stay at full power when I reduce pedal torque at higher speed...

hi whoosh I dont see that kit on your site, only on other peoples (At the same price as the BBS01)? and its a torque sensor right versus BBS cadence? With torque sensor am I right that I am going to get better shifting (versus your BBS without gear sensor)? adding gear-shift sensor to BBS would...
