That controller is only rated to 7 amps - that's not enough current for any meaningful ebike motor - maybe you have a different use for it?

Thanks for clarifying all of that. Given how successful OSF has been in improving the ride for the TSDZ2 , it would be daft if Tong Sheng didn't incorporate some of the better features into the TSDZ8. If that is the case and from your experience that seems to be highly likely, then that is...

I'm glad to see that the TSDZ8 is working well for you and I look forward to hearing how the motor performs over time and you've some serious miles 'on the clock'. I regularly ride each of my two TSDZ2 bikes (both OSF) and find power delivery is smooth too and I can't imagine what 'smoother'...

What a steal at £80 - well done you . You say 'risk' - providing the bottom bracket is the standard 68mm long and the BB area clear of any obstructions being in the way of the motor (and being able to mount a nice rack battery - none of that hideous Hailong stuff for that bike!) , what other...

And just in case the OP hasn't come across the term 'dropout' this is the distance between the bike's forks where the wheel drops in, as per pic. Aka OLN and OLD.

@Garry Hallam -what specifically was it about the OEM battery build that you didn't like? That single picture doesn't show much - there's many many aspects to a battery build that together give a quality construction. And out of interest, as this is going to be your first battery build, what...

Well, there's lots of support from members to have a go at building your own wheel, a notion that I fully endorse for all of the reasons given - just go for it! There are so many on-line resources (and free at that) to help the new builder, but personally I like to refer to my paper printout...

It is quite normal for rim brakes to wear wheel rims down although if you've only done 5,000 miles ish, then this is a bit on the low side of normal. Having said that if you've done a lot of braking in dirty/gritty conditions and especially if the brake blocks have ended up with metal framents...

Hi @az - I had to remove a bit of frame on a brand new bike that I converted for a friend (as per your red bike in post #22). IMHO there was absolutely NO detriment to frame integrity and that conversion was a couple of years ago and no problems since. Mind you, I didn't tell the friend what I...

Hi @Woosh - back in your first post in this thread you said - - why is the anti-torque hanger no longer need (that's really good new BTW) - is the 'triangular' retaining clamp more serrated than the one for the TSDZ2? And can you tell me what is the gap between the crank axle housing and the...

Without fitting the grooved 'vee' bracket in yr pic 2, the motor would rotate in the bottom bracket shell, or at least it would in 'normal' bikes. You say "..... not in my case" - why is that then? Pic courtesy of @Woosh TSDZ2 installation manual.

I think what @peterjd is getting at is the pleasure that a light weight non e-assisted bike rides like compared to the more heavier e-bike machines. That's very much a subjective rider assessment of course and those with high powered e-bikes who use little of their own leg power won't...

Tony, I'm not looking to agree or disagree with the main thrust of your post, but I'm guessing you'd prefer to be correct in what you say so I hope you take my correction in the spirit intended? Part 'P' of the building regulations does allow some 'DIY' electrical work, e.g. Best wishes.

..... as in the Brompton is not there yet? A few years ago we (wife and self) contemplated buying two Bromptons and flying off to NZ for a drive/cycle/walking holiday. I borrowed a friend's Brompton to try one out and really could not adjust to the ride, so that was the end of that idea...

Thanks for the reply - much appreciated. The above is the method I use too and as you say the 'Wh' re-charge figure is going to be higher than the actual 'Wh' discharge, but by how much I can't tell as I've no calibrated instrumentation to do any comparisons with, but the method used is...

An interesting setup (cadence mode) to consider for those wanting that sort of assist which is more akin to those choosing a Bafang mid drive. Out of interest, what is your setup for measuring watt hours per mile? 6.2 Wh/mile is a really low level of power consumption - I'm guessing the all up...

That Zone 2 article was interesting and as a Torque Sesnsing mid drive rider, I'll not feel guilty about my 30 mile ride tomorrow (to my fave cafe for coffee and cake) in ECO mode - lol!

I've never looked at wrist mirrors before this post - first thoughts are: Puttint them on before ride detracts somewhat from the spontainity of just jumping on your bike for a ride not great for wrist watch wears if riding on straights (Pic A), then your hands are going to be near enough...

A couple of notes for those looking to use OSF for the first time: EDIT: an update on older versions of SDCC below > I've just got a Win11 laptop and wanted to be able to program my TSDZ2 which until now I've been doing using my Win10 laptop. > I revisted the Github page (by Embrusa - link) to...

Welcome to the forum. I see you're asked about conversion kits in another post - cross posting the same question will annoy some.
