A new kit is on the block

[Woosh]

Introducing the new 85TS kit:

Only 3 components to install: the motorwheel, the battery and the LCD.
The motorwheel in this kit is state of the art as far as conversion kits go.
Inside the cassette freehub body, the maker has integrated a torque sensor, a pedal assist sensor and a speedometer.
This high degree of integration is the key to deploy this kit on high end bikes, even those with carbon frames and pressfit bottom brackets.
The battery uses also the latest 21700 cylindrical cells from Samsung, 36V 20AH or 720Watt Hours, enough for a whole day of cycling even by the most enthusiastic cyclists.
The colour LCD is clear and gives excellent result even in bright light.
Give your next bike this best kit at the moment.
It's so simple!

It looks pretty good. I have some questions:
Current control or speed control?
Does the torque sensor system give proporttional power, fixed power or stepped?
Can the throttle be set to only work when you pedal?

Looks great - is it 201 rpm motor ?

 

[Woosh]

Current control or speed control?
Does the torque sensor system give proporttional power, fixed power or stepped?
Can the throttle be set to only work when you pedal?

Current control. There is no jerkiness of stepped power when you change your pedalling or change the assist level but best to have a word with Andy. I am rubbish at describing how the bike responds.
As with all kits, the best way to find out is to test it!

 

[Woosh]

It should be 230rpm. I need to test it to be sure. The demobike does not have the throttle.
I need to install the throttle to test the maximum speed derestricted.

 

[kevsbike]

Cool. I like the idea of the torque sensor on the cassette. I was looking at a Geeko kit, which has a cassette sensor, for one of my 26" bikes but although both can have a front disc neither have disc mounts at the rear, is a rim with a braking surface an option?

 

[Woosh]

You can use rim brakes at the rear. The 85TS rim has V braking band. However, you need to know that v brakes require more maintenance (use softer rubber compound, keep the pads parallel to the rim and centered) to avoid excessive wear. When the bike is motorised, people tend to ride faster which wears the braking band faster. My advise is to fit disc brakes at the front if at all possible. As about 70% of braking is done at the front, disc at the front will reduce wear at the rear and extend the life of the braking band.

 

[matthewslack]

Is the clever bit available as a spare, or would the whole motor need to be replaced?

 

[Woosh]

At the moment, I don't have spare motor lids so the whole wheel needs to be swapped out. In the next few months, I will of course keep spares to simplify servicing.

 

[Woosh]

Andy checked it this afternoon. The battery on the demo bike was about 30% full, maximum speed unrestricted is 21.3mph.
The bike is put on charge now, we'll check again tomorrow.
Hope that gives you an idea.
The LCD itself has 60kph as maximum speed limit. You have of course to put the speed limit back before riding on the road.

Oh thank you - definitely not 201 rpm then, - was the 21.3mph the unloaded speed ? on a 700c wheel or 26"

26" Peter. It's still early days. Although I have had the preproduction kit for nearly a year, we still need another 6 months to know the product better before expanding the range of motorwheels. I truly hope that its innovative components get the success they deserve.

 

[Wayners]

Any option for a rack battery? I have a step through ( girls bike ) I want to convert

 

[Woosh]

Thank you for asking. I will have the 85TS kit with rack in a couple of months.

Customer feedback:

Hi Andy,
Thanks for the bits. I finally managed to find time to fit the kit and try it. All I can say is AWESOME.
The kit took less than an hour to fit - the back wheel just slotted in and I did not even need to re-index my gears. The longest part was tidying the cables onto the frame. It is literally plug and play.
The power assist is delivered incredibly smoothly and powerfully, and even on setting 5 does not ever feel like it will run away from me. The power feed stops instantly as you reduce pedalling effort. And the control panel is simplicity itself.
I couldn't be more pleased.

Andrew.

Daft question. What does the 'SX' designation on the motor stand for?

 

[Bikes4two]

Hi @Woosh

Inside the cassette freehub body, the maker has integrated a torque sensor, a pedal assist sensor and a speedometer.

I love the simplicity of that freehub body but out of interest, how do the torque signals and PAS sensor signals get to the controller that is housed in the battery compartment?

Is it via bluetooth or other wireless method or is the speed sensor connection in the multi-way motor cable 'multiplexed' in some way?

The Mahle X20 system hub motor has the same functionality (but massively more expensive) as does the Boostbike kit (but no torque sensor in that one I think?).

What ever, it is great to see how these products are evolving and the inclusion of torque sensing will appeal to many.

Thanks.

I am not certain but thought it's series X with two staged gearbox.

The connector has 4 wires. I am not certain but thought it's ground, 5V supply, data transmit and data receive.

The 100SX appears to have the same physical dimensions as the 100H. The only difference that I can see is the stated power 250W/350W. I wondered if it was just a derating code for the European market.
