March 18, 20251 yr 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.

March 18, 20251 yr Author 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? 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! Edited March 18, 20251 yr by Woosh
March 18, 20251 yr Author Looks great - is it 201 rpm motor ? 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. Edited March 18, 20251 yr by Woosh
March 18, 20251 yr 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?
March 18, 20251 yr Author 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.
March 18, 20251 yr Is the clever bit available as a spare, or would the whole motor need to be replaced?
March 18, 20251 yr Author 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.
March 18, 20251 yr Author Looks great - is it 201 rpm motor ? 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"
March 18, 20251 yr Author 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.
March 18, 20251 yr Any option for a rack battery? I have a step through ( girls bike:) ) I want to convert
March 18, 20251 yr Author Thank you for asking. I will have the 85TS kit with rack in a couple of months.
April 7, 20251 yr Author 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.
April 7, 20251 yr Hi [mention=6303]Woosh[/mention] 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.
April 8, 20251 yr Author Daft question. What does the 'SX' designation on the motor stand for? I am not certain but thought it's series X with two staged gearbox.

I am not certain but thought it's ground, 5V supply, data transmit and data receive.
April 8, 20251 yr I am not certain but thought it's series X with two staged gearbox. 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.
April 8, 20251 yr Author 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. They have pretty much same specifications. The wattage is part customers' demand to comply with local regulations, part choice of copper wire. I can ask for maximum current while rated and labelled as 250W. For 48V, I usually ask for 20A max. That's plenty enough of safety margin. You can distinguish between similar models by their weight and choice of gearbox ratios.

I wondered if it was just a derating code for the European market. The rating comes from the speed you use it at. If you restrict it to 15mph, they call it a 250w one, and if you let it go to 20 mph, it's 350w. The problem is that it doesn't tie up with our legal definition. If you buy enough of them for a specific restricted 15.5 mph bike, they will label it as 250w for you, the same as any motor manufacturer.

If you buy enough of them for a specific restricted 15.5 mph bike, they will label it as 250w for you, the same as any motor manufacturer. I asked Yosepower a while ago about the AKM95 motors that they supply. They said their 95RS 350w freewheel motor is 230rpm with 4.4 gear ratio. Their 95RX 350w cassette motor is 240rpm with 8.15 gear ratio. The 95RX 250w cassette motor is 205 rpm with 8.15 ratio. From that I concluded that RX denotes lower gears.

If you look on the Aikema website, they're all listed as 27/32km/hr, so I don't think that's it. For some motors, they make different windings and different internal gears for the same motors, depending on the size of the wheel that you want to put them in. I would have thought the RS and RX are more likely to be something to do with the construction than the performance parameters. Both versions have 40/18T two-stage reduction gears. Both have sideplates fixed with screws, so it might be the windings that are different. The only differences I can see is that the RS is heavier and gives less torque from whichever test they do., which contradicts with actual experience on hill-climbs. We know that the ones that Yose sell have different speeds, but that doesn't tie up with what's on the Aikema website, so it's all a bit of a mystery. Yose are correct in what they're saying. members have tested them. the 250w one is definitely slower, but has more torque for normal hill-climbing, which ties up with more turns in the windings. Yose sell a 20" kit that looks like it has one of the same motors, but that will need a 328 rpm version and they say it's 250w. The problem is that we can't say that any other supplier doesn't have different versions of those motors that are wound for different speeds. I think I stick with my original statement that Yose fix the speed of the 250w kits to 15.5 mph and leave the others unrestricted, and the RS version of the motor with maybe more copper in it is more suited to lower speed grinding.
