Has anyone heard of or tried Toseven mid drive?

The hall sensor has a magnet near it, and it is the movement in the magnet in relation to the hall sensor that senses the torque. The coils are an inductive method of transfer of this information allowing for crank rotation.
Didn't I read either in this thread or on the ToSeven blog pages that the torque sensor uses strain gauges to measure the torque? Yup just found it in post #85 from Alex.

You are the only rep I know who answers by ridiculising those who want to talk to you. I have no problem dealing directly with Chinese sales and tech support people, they are always curteous, detailed and helpful.



Look at every single thing you have posted since we started. Nothing but criticism. The rotors are poor quality you cant say why? The materials are poor but you cant say why (you have not even asked the composition) and can only compare to a motor 3x the price. Something clearly designed to a completely different price point.

Everyone knows these are designed and made as an entry-level torque sensing motor to the market.. and currently ours is the most refined of the designs on the market. The reason is obvious

You are the one who has mocked and ridiculed our products since we came on here.

I was nothing but polite helpful and courteous in the beginning, I personally wrote you and sent you my phone number so you could call me and discuss anything you wanted. Instead you choose to try slander our products on here. Dont bother to write or call me, and email the other staff instead.

Im sorry but when you claim to be the expert and then slag off a companies products..... (And openly sell older models designed by the same man) you leave yourself open. You are selling motors made of the same materials etc but you say ours are poor? You are selling an older design but ours are poor?

I made a statement at the start about what we had done. One i know to be true. I was then the subject of attack. Slowly what i said to be true is being realised as factual. Most people would realise that the same man isn't going to continually improve a product then leave one company to start another so he can make worse products.. its his lifetimes work


I have seldom received any politeness or courtesy from you, but have shown i am willing to show you that when you admit you have made a mistake, were wrong or have prematurely judged our products. I did it a few posts back but then you went back to unfounded allegations on materials and quality..? Why what does it achieve?

The presumptive attitude towards us as being just a copy and of poor quality is what led to this mess. Im more than willing to improve relations but i expect that all our staff are treated respectfully

We will make mistakes, not everything will be perfect but when things do go wrong we will stand up and own that mistake then go to work rectifying it.

I am not an expert on everything and don't claim to be, programming is a weak part for me, blacklite from here reached out to me. Ive answered everything i could and quickly understood he has a really in-depth knowledge of these motors and the programming. So hes now at the top of the list with distributers to be sent a motor next week.. because we value his insights.. as well as his constructive feedback. This is the type of relationship i like to foster because my time is limited and im looking to learn as much as i can so i can keep improving our products. End user feedback is at the heart of that


Its obvious that you have begun this with a loaded viewpoint. You admitted that a while back.. saying how do you think it makes you feel when you see our sales reps posts? Because you have been selling tongsheng for years and you like them.

Well our head engineer poured his heart and soul into designing and making those motors you sell and now into these. So i should not talk about the improvements hes made because it hurts your feelings? We have no right to talk about his work because it upsets you?

Its easy to be courteous and have an open working relationship with someone, i tried that with you..again you didn't engage me you decide to come on this public space and try to constantly pick holes or problems and usually not in a constrictive way.


If you want to change the relationship at any point feel free, in order to do it your criticism would have to change to having legitimate grounds. Currently you are in the position of being open to being viewed as bias because you sell tongsheng and also very hypocritical for the same reason, again because it public knowledge who designed both

So please don't just look at a picture of a rotor and say its crap. Anyone can do that. Let us know what's wrong with it and if reasonably possible we will improve it.


At to7 we are going to engage in a programme of constant improvement and innovation. We have plans for motors that bring new features not seen on any other products.
But we are quite new and so we cannot reveal everything for obvious reasons its a very competitive market.


Again. Im open to a courteous relationship based on mutual respect

He's testing you and sounding out the new motor. He wants to know how much profit he will make from selling them. You're making it difficult. He has lots of experience of repairing motors that had problems, which wipe out his profits. He doesn't want to go through all that with a new one. Most of the questions are irrelevant. You're all getting hung up on details that don't matter. It's intellectual masturbation and battle of wits. None of it matters.

My comment was in relation to the TSDZ2 torque sensor.

I haven't seen the To7 motor in person yet, only what I have read and seen in pictures in forums, and in conversations with alexfnoble. I'm hoping that it has a torque sensor that is much more consistent in output than the TSDZ2 one that is highly variable in range and linearity across both different units and also with changes in temperature. It's one of the things I really want to test on the new DM-02. That consistency is one of the keys to achieving a responsive and consistent riding experience.

Back in 2013, I was selling a crank drive kit from BEWO Technology that I called the TCM.

Here are some pictures of the Bewo parts that we still keep for servicing that I have just taken for you. Do remember that they are made 10 years ago. A lot of progress have been made since.
Their prices are about same as the TSDZ2.

The good point about the Bewo design is it can use an external controller and also, with some modifications, have a torque sensor. Also, the fins are in contact with the outside air.





So after 10 years, I know a bit about strengths and weaknesses of low cost crank drives. The point about the picture of the Bosch motor is to show how to make a good kit.
Compare the Bewo parts against yours and comment if you like.
The people at Bewo are very easy to work with, especially their rep, Shaun Chen.

In my student days, electronics were nothing like it is today. Sometimes I wish I were born 20 years later. I would have participated more to the e-bike scene.

Getting back to the subject, the thread was normal until you started to post. The impression you give is nothing like that of a usual low key, technical, to the point rendering of the new shiny kits,that any Chinese rep or their local contact / importer would have posted.
Your corporaty, brashy, abrasive, big boy powerpoint bulletty posts are not what the forum is about.
Think about it anyway.

the benchmark for torque sensor in any low cost TS crank drive is the straightforward bafang bottom bracket torque sensor. Also, I'd like to see a cycloidal gearbox.

Which Bafang crank drive motor, for DIY install in a standard bottom bracket, has a torque sensor?

For things to improve this would be my top four -
Heat management between stator and case
A proper FOC controller.
Less play in the axle / better and smoother bearings.
A more consistent torque sensor that doesn’t have wildly variable values between units.

Notice how a lot of these are things that To7 have claimed to have addressed.

I personally can’t wait to use one and see if they have.
my concerns about any new low cost products from China:

Fortune cookies or lucky dip
Vapourware in the kind of 'yes, we've fixed it'
The thing is made of cheese
The thing does not survive 7 days in a salt fog test
The thing rusts after a drop in a deep puddle
The thing rusts after a day on Southend beach
The thing rusts after a year
The thing snaps at various places
No firmware update, no configurator, by the backdoor or front door
No tools
Gunked up
Controllers talk only to one or two LCDs
Sales only, we don't do support
Warranty? what warranty?

That's why when you find a good product, you stick with it because if you sell it, you have at least a potential 7+ year relationship. Until now, I deal only with Chinese people. If I buy to7 motors, I'll have to be nice to Alex too.

This emphasis on PMs is really quite concerning. I hope you'll post your findings on the open thread, for us non-distributors who King Alex of Toseven and Subaruland will not answer the questions of.

the king of the DIY install in a standard bottom bracket market is still very much Bafang BBSes. If someone started to cut into their market share, I am pretty sure they will release their TS versions.

They don't have any and have not shown any interest. I approached them with it years ago and they told me it wasnt part of the market they are interested in. Its not what they are focused on at all now. Right now you have us or cyc
