Re: New "TSDZ2 Torque Sensor Central Motor"

Id be happy to buy a controller thats been flashed and has the correct connector on it (6 pin) By the time ive read pages of info and wrapped my head around it all to the point where i can make it work.. i could have done a few hours overtime and paid someone to do one for me. Might seem lazy but t...

Re: New "TSDZ2 Torque Sensor Central Motor"

Is anyone getting some regular creaking noise from the axle while pushing the pedals hard ? Going up hill or just accelerating on flat roads same noise... I have regreased and tightened all the elements that hold in place the motor on the frame to eliminate this possibility, so it looks like it's c...

Re: My econo-e-bike (long read, sorry)

Very interesting, thanks for the detailed post - looks like a setup that works really well for you. That's exactly the system I want to find (at a similar price) in Australia, I'll contact the seller again and ask if he'll ship to Australia.

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

Another option would be to attempt to install my TSDZ2 mid drive somehow on the bike (GT Sensor 2). I think the bottom bracket thread is the right size, but because of the design its almost 'floating'. Someone posted some pics of the bottom bracket on another ebike forum - not sure how / where motor...

Thanks everyone for your useful, thoughtful and helpful comments - so much knowledge here! Going to do a bit more thinking and a bit more research before making the plunge!

I tried to fit a 34t tooth chainring to my TSDZ2 but I'm not sure if its supposed to go on the inside of the 'spider' that holds the chainring (where original chainring was) or on the outside (where chainring guard was previously). When I fit to the inside of the 'spider' the chain rubs against the ...

Re: TSDZ2 versions and throttle

I don't think there's any reason not to go the throttle version - I have it. I don't use it much but useful to have when walking with bike, or if I am just jumping on bike quickly and can just give a quick blast with throttle (note on TSDZ2 throttle doesn't give full power / boost).

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

These 'roads' won't be on Google maps, but I might be able to find similar ones and map those to get a comparison. Also have a couple of biker friends who might have a better idea. All except very short 20 metre hill I think is less than 20%, maybe 15% at a guess, but thought I'd put 20% in simulat...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

If you do want to make a bike that will carry that load up the hills on 1000w, you need that 1000w kit in a 20" wheel. Then the bike will need some modification to run that small wheel in back. See the link below for bolt on longtail. Or you build a bike, like the mixte longtail link below. Or ... ...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

One thing I did notice from the simulator though is how much (or little) assistance I'll get from the motor on the hills... If my speed drops to <10km p/h, the motor efficiency drops to only 25% or whatever, then I might only be getting 250w input from the motor, with the other 750w wasted as heat. ...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

20% is pretty intense. You will start to feel like you're going to tip over backwards, and traction will be a big issue on unimproved surfaces. I get rough grade values with Google maps - select the section of road with beginning and end markers and get bicycle "directions" in km. Distance and elev...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

looking at the simulator, what motor would I select for a 1000w DD with 470rpm? I guess that's close to 9C 2707, which I understand to be 9 rpm/v. Depending on what voltage that 470 rpm goes with. I hope you can find something slower, though I don't have any suggestions. Watch the "efficiency" figu...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

Or will I need a more expensive geared motor (like the Mac with 12t winding)? Don't forget to use the ebike motor simulator. Not sure the Mac will cut it, based on the simulator, on a 12% grade, with 352 lb payload, the motor overheats in 5 minutes. https://www.ebikes.ca/tools/simulator.html?bopen=...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

Interested in the idea of a smaller wheel, but wouldn't a 24" or 20" rear wheel affect the bike significantly? Will have a look at geared rear hubs again. Think I need to decide between a cheap kit that will get me started, but might not last for ever, and saving up and waiting a bit for something h...

Another quick question - how do I remove the crank arms? I purchased a smaller chainring but don't know how to remove the crank arm. Do I need a special tool?! Yes. It's called a "crank puller". About $15. You'll also need a bottom bracket tool to remove the bottom bracket. It looks like kind of li...

I'm in a similar situation with regard to wanting grunt to help get me up hills rather than top end speed on the flats. Interested to see comments on this one. I've looked for a high powered geared rear hub, but most of the ones i've seen are rated at (nominal) 500w (e.g. Bafang BPM and MAC). Anothe...

Re: Would a 1500w Direct Drive Hub Get Me Up Short but Steep Hills on Full Suspension Bike without frying?

Looks like the price is right and my experience with a similar DD motor would say it is entirely possible to do as you suggest, especially if you are willing to assist pedaling and use low enough gearing so that you are in sync with the motor. At worst you may find the controller to be insufficient...
