Has anyone heard of or tried Toseven mid drive?

[guerney]

did anyone bought it yet ? can we see video showing benefits of new build ?

I will not buy this Toseven mid-drive for a few reasons, most notable of which being users will be stuck with stock firmware for years, and it's early version firmware with no configuration tool provided, and no firmware hacks exist. 12 in stock now, not 13 as stated in post #134 - somelemmingone somewhere has bought one:

I'm not planning to be on the bleeding edge, maybe in 12 months time if and when the motor has proved reliable and the gremlins fixed.

How much of an issue is the heat build-up on the tsdz2, I would like to think that the 250w configured variants in stock firmware should be quite tolerant, especially on torque sensing rather than just throttle. I know lots of folks have the more powerful variants or push the envelope with osf and higher power configs - and of course people will want to continue to do similar so better cooling is important, just keen to understand at what point the problems are likely to start.

The stator is tightly fitted into a machined housing now.

It will take your company many years to gain significant mid-motor market share, if you don't make a firmware configuration tool generally available now.

 

[Bogmonster666]

Given the apparent pricing, I do think there is an uphill battle. It really does have to prove it has solved the tsdz2 issues to justify the considerable price difference. Sure, the tsdz2 is a bit cheap and nasty but it's a known quantity and it is cheap! For pushing double the price, is it twice as good - for my modest needs I think it unlikely.

I would like to think potential suppliers have evaluation samples and we should start hearing 3rd party opinions soon. They don't appear to be selling like hotcakes on PSPPower just yet though, not holding my breath.

I am tempted to add a TMM torque sensor to the throttle of the BBS01

You should do this @Woosh . Can that sensor be fitted to any bike?

can you please take this somewhere else ?

why ? if this could be configurable via display ? its way better imho . osf for tsdz2 came from need , i doubt that community would spent so much time to provide something already existing...
somehow factory motors work out of the box without any customization tools and people happily use them with no urge to fiddle with . they are just precisely calibrated and configured

not sure why but when i see chinese video of the product it's terrifying that they seem to be shot by random parking sweeper with potato wrapped with old sock ... i can't imagine that they have money to start serious company with all staff and machines and then are unable to shoot a decent flick and have somebody to post on yt ... and how com they are unable to provide decent translation from chinese to english of manual it's beyond me ...

Yes.

Companies such as Apple see deeply enough to understand the importance of cultivating, controlling and jealously guarding their brand image... Chinese companies won't bother because by they appear to be about selling as many products as possible, as quickly as possible, while spending as little as possible on marketing.

p.s. I hate Apple.

Why on earth would so many people develop and use OSF if:

but when you want to sell a product and have invested 10M$ in factory and have it produced and want to go worldwide - 1000$ in professional shoot informational video is nothing , literally nothing ...taking random worker to shoot this with his broken cellphone is contradictory to intent ...

i meant factory motors like yamaha / bosch / brose etc , but also tsdz2 out of the box worked better than osf - in terms of tensometer reactions . osf primarily gives you ability to limit or expand power and top speed - fyik

What is tensometer reactions?

Still 12 available lol. Unleash the configurator for gawd's sake.

torq sensor

 

[Woosh]

Can you explain how the torque sensor on the to7 motor works?

I'm very Interested in buying the 1000W toseven motor (30A).
What displays are supported? Can i use my existing TSDZ2 display? Is the communication protocol the same as the Tongsheng?

Can i use (overvolt) a 52v battery with the 48v toseven motor (52 * 30A -> 1560W)?

Displays are on the website

https://to7motor.com/

The tongsheng displays are not compatible and its a different protocol. It comes as a kit so will come with a display

Yes you can use a 52v battery

The To7 and TSDZ are different motors and use different software/firmware.
