How steep are the hills. Or perhaps what gradient of hills can you currently get up adequately with you current configuration Vs what gradient hills do you want to get up? E.g. if you can comfortably get up only a 10 % hill today, then increasing the current by 30% is unlikely to get you up 25%...

I have not heard about the outer case screws and I think most of these are hex machine screws so you can get a good purchase on them? I think some regular maintenance is required anyway so by my thinking, if they are not left in situ for years without even being removed maybe you could have a...

Wow, that's impressive, and the difference between the tsdz2 crank and Bafang crank is very small. My thinking is 10mm isn't going to make much of a difference. I think lower gearing is where I need to start. Thanks for your help once again

I'm fitting a slightly bigger cassette this weekend (7 speed wheel so only going from 28 to 32t) and I will get a straighter crank arm, probably a Bafang one (@elinx 's post looks like the Bafang crank arm will help quite a lot). I'm keen to persevere with the tsdz2 if I can - I want a moderate...

I think the q factor and particularly the chainring side offset peddle is causing me ankle pain. In fairness I badly sprained my right ankle with an avulsion fracture 9 months ago and my ankle hasn't been right since. However, after a longish ride my ankle starts clicking and becomes quite...

How about a little compartment built into the case where one could keep warm a bacon and egg sandwich for the brunch stop?

That is reassuring, no idea how many tsdz2 motors you have sold, but if this was a significant problem for the typical UK user I would image you would have found out by now. I expect most of your kits go to cyclists who want to pedal and want to tackle typical UK hills. I tend to think we hear...

And this is the crux, it's the uncertainty. Proper cooling and thermal monitoring are really the only solution. Assume 48v at 15a and 75% efficiency. That's a 180w heater in a small insulated box.

I believe, but could be wrong, that the @Woosh supplied tsdz2 motors are 15a? These are the 48v 250w variant woosh gets from the factory. I agree that the OSF benefits I'm interested in are not more power: 1) Field weakening for higher cadence support. 2) Better motor control for less noise...

This is exactly the problem, it's really hard to know when things are getting too hot. The person discharging a battery at 18 amps was certainly not operating the motor in typical conditions....and I don't live in mountains... Does a 10 min blast on turbo up a steep hill at 65rpm on stock...

I have heard that the dm-01 does not have the air gap, not sure if this applied to the dm-02 as well? Engineering wise, it feels like a simple fix. I don't have osf but still try to be easy on my tsdz2 as I really am in the dark about how hot the motor gets. Most of the time it's fine I'm sure...

It does appear on paper that some of the tsdz2 shortcomings have been addressed. Obviously will want to see that reflected in real world experiences. As for the motor incorrectly mounted, I am aware that the tsdz2 case is prone to shearing if not mounted correctly. I think there are some open...

Maybe you have found a simple solution to do away with that pesky torque sensor? How about adding a wind speed measuring thingy so assistance can be increased when cycling into a headwind. I know I'm increasing the design brief but let's shot for the stars...

I'm not feeling I'm getting anything much from this thread other than a headache and a sense of regret I ever starting to follow it. When can we expect to see reviews of this product from a range of independent reviewers? I would like to think that functional questions could be resolved very...

I was just having a bit of fun. I personally have a modest rear light: https://fawkes-cycles.co.uk/smart-rl317r-1w-superflash-1-watt-rear-led-light-p11385 And another cheapo rear as I have had lights turn themselves off on bumpy surfaces. Numerous studies have shown that pedal reflectors or...

Maybe they have some vacancies?

Possibly there is a bit more room for a smaller dished chainring on the to seven than on the tsdz2? Whilst lots of folks want bigger chainrings than the tsdz2 standard dished 42t, I would potentially want to go as low as 36t with my 26 inch wheels. For those with a 29er I can image the 42t is...

Yes, they are the sort of thing I'm after. I don't want off-road tyres and in reality rural roads are probably less covered with glass, hyperdermic syringes and other sharp roadside debris than city roads. Maybe more roadkill though....although even that is debatable...

Yes, I don't think I'd fully registered the price. The other week I could have bought a Bosch based complete bike for ~£1600 in the sale and with discounts. Not far off that with the cyc @~$950 + battery + donor bike...too spendy for me...ok, so the Bosch motor may need to go to Germany for...

They are both way too spendy for me...I can't give sound advice as I couldn't justify buying either of them. As for range, what range do you require and what do you get out of your current 400wh? I guess if you need the range you need the range. 400wh to 500wh battery upgrade only buys you...
