Oh could very well have been the case as I get used to this bike and thinking of it now, at a slow cadence the Bosch won't output full power so I guess it's a way of saving the motor, though the Bosch also has temperature protection something the TSDZ2 does not which is strange considering how easy it would be to add a simple temp sensor.Climbing the steep hill in level 4 should not have been a problem at all. Methinks you may have had the bike in too high a gear.
No cooling mods, I might look into that.In a way the motor is like your body... it can't push a high gear up a steep hill. Shift and ride like you normally (or should normally) do and it'll go up those hills easily.
I don't recall, but did you get yours with the cooling mods pre-installed? If not... and if you intend to climb hills like that, especially if they are of any length, your motor is going to overheat and have a short life.
The throttle is really just to relieve the legs but I was surprised at how weak it is on throttle alone especially on the hills.TSDZ2 throttle is really an afterthought. It won't go fast or far. Just use it for starting out or putzing around slowly. If you want a throttle bike get a BBSHD and a corresponding high amp battery.
I'm trying to compare to the Bosch Gen 1 50 Nm and on a steep climb today at full power I don't remember having to pedal that hard with the Bosch on the same hill and with the Bosch my legs weren't going as fast either, definitely going to take the Bosch up that hill tomorrow to compare the two. The hill is around 15-18% if not 20% at the steepest part.Put on a smaller chainring. Ride in a lower gear on the hills. Fit a different rear derailleur and change the cassette to one with a 50t big cog. I guess I don't understand your issue on hills. My TSDZ2 will easily climb those really steep grades. Not at 25 mph, but at a goodly pace. And yes, forget the throttle on hills. It will be useless.
No slow grinding, don't want to be pedalling faster than I was today which I consider too fast because the motor obviously hasn't the grunt, I'm used to mid drive so I know how to use the gears.A note on cadence.... we all have preferred cadence, but when climbing steep there are other more important considerations. If you are doing with what I suspect is a slow grinding cadence and expecting a high speed, that is a formula for failure whether on a pedal bike or a TSDZ2. The gears are there for a reason... to make it easy, especially with the motor. That's the real beauty of a mid motor. Just use them. Good luck.
You might need to tighten your crank arm boltsI forgot to mention, there's a loud and annoying creaking noise when pedalling when the motor is on especially.
Thanks, I'll give it a try.You might need to tighten your crank arm bolts
I wouldn't be surprised if you've already cooked your motor, at least a bit... I don't have any idea on the power comparison with a Bosch but based on your earlier post about climbing and the case being hot I think that's a distinct possibility. The motor is pretty insulated in the case so heat has to work hard to get out, so if the case is hot the motor is a lot hotter. Hopefully not but if so that may be affecting the power output if the motor magnets are demagnetised etc. I've cooked one motor just riding around town and now I have all the cooling mods and temp sensor installed.Just back from the test with the Bosch and as I suspected it's notably more powerful than the Bosch, incredible.
The TSDZ2 is rated as 80 Nm ? absolute horse shit. Bosch is rated as 50 Nm and it kicked it's ass and not only that, the casing of the Bosch was hardly even luke warm.
What would I estimate the TSDZ2 is rated at then ? can't say for sure but it's less than 50 Nm. Probably most of the power turning to heat.
The TDS2 has an 84? cadenc e limit, so if you are pushing 120 up hill you won't get any help.No slow grinding, don't want to be pedalling faster than I was today which I consider too fast because the motor obviously hasn't the grunt, I'm used to mid drive so I know how to use the gears.
I'd say that 80 Nm torque figure is nonsense, I'll know more later when I take the Bosch back to that same hill.
No idea what cadence I was pushing, but there was output from the motor.The TDS2 has an 84? cadenc e limit, so if you are pushing 120 up hill you won't get any help.
