Question: I've been looking at the specs and it states 250w however the controller is set to 16A and the battery is 48v.

So hit 120 miles going on a lot of off road trips putting the motor through some tough tests, i'm happy to say its passed with flying colours and nothing has come loose etc since adding the loctite blue to the screws etc.I therefore can’t just give you two range numbers in your specific case for a 48V, 12Ah and 17Ah battery. Battery - The number of hours an e-bike can travel highly depends on its battery capacity and motor type. A motor that drains less energy from the battery can power a bike for long. Disc size again depends on intended use, weight etc. A 203mm hydraulic on the front is a serious stopper, but use it with caution in the wet/ mud or you'll end up on your arse. My 160 rear/ 180 front is the perfect compromise in my opinion. I'm debating upgrading to a four-pot caliper on the front but that's 'coz I'm a spec tart. No. The 48V controller is the same. Some dealers reprogram the controller, we don't. They are programmed by Tongsheng. I went out with a friend who has an expensive hiabike xduro nduro bike and we tried each others bikes and did a bit of offroading. It compared very favourable with the haibike. Maybe I'll do a more detailed review.

Andorra, Croatia, Iceland, Liechtenstein, Macedonia, Norway, Switzerland, UKRAINE, Vatican City, San Marino, Malta, Cyprus New version TSDZ2B has two clutches designed on the main gear, Main gear is disengaged from the chain during riding, So it feels as easy to ride as a bicycle; Old version TSDZ2 rides with main gear, Main gear turns with small gear.So the riding resistance is larger than bicycle Controller failure – the TSDZ2 doesn’t like prolonged load and can overheat, particularly on long, steep hills.

If your purpose is to get fitter, the Tongsheng TSDZ2 will definitely be the better choice for you. The Tongsheng will provide a much more natural ride, in which the motor really is an extension of your body. The Bafang motor will feel a lot more as a standalone assistance motor. The ‘Sprag clutch’ or one way bearing has also been known to fail occasionally. ***This issue has been rectified with the latest ‘B’ model.

So, when you are in first gear, you get the most torque which is of course when you need it. As you move up the gears the assistance becomes less pronounced. The TSDZ2 is “torque-sensing”– if you pedal gently, you get a gentle assist; if you pedal hard, the motor works harder. This differs from the other common mid-drive kit (Bafang) which is cadence sensing – you set the assistance you want, and so long as the pedals are turning, the motor gives that flat level of assist.
