This guy reminds me of Jim Carey the batter tender! Or the cable buy! LMFAO!!! You forgot to mention parasitic discharge due to a faulty USB port!!!!!!!!!! REEEEPORT!!!!!

Hope to get one in oz :) soon

Sounds awesome, good luck. Finding a way to make the back peddle regen work too would be awesome.

Hi, great overview this incredible machine😀. I'm asking myself ... do you think it's possible to stick flexible pannel on the body of a velomobile ?

“Noooooo!! That’s sick” The best solution is usually the simplest!!! Incredible!

SOLD! I want it.

This design is very innovative and delicate, but I still find it quite bloated. Speaking from my own experiences ,When Comparing with hub motors with no gears, hub with planetary gears, and ratchet gives about 2% more range because it has less drag when free wheeling. This design enables regenerative braking, which gives about 5% increase of range, so, in total mess than 10% of increase of range can be achieved. But the biggest drawback off hub motors, doesn’t matter whether they are geared or gearless is that they are heavy, usually more than 5 kg is added to the bike When installed. So I still find my design the best: a small brushless motor with chain drive mounted on brake month, it’s very light less than 500g added to the bike, end it can do regenerative braking you don’t even need rear brake because the motor brake is very strong. The top speed is more than 50 km/h and it’s very efficient. and the most important theme is, it’s very a simple design😊 here’sa demo: ua-cam.com/users/shortso0DVQSLvBlw?si=tLd9lJXA1vzKMOpc

Where can I see you guys in Eurobike?:)

Can we imagine a mid-mounted motor with an integrated disc brake with this system ? I'm sure THIS is the future. Maybe the disc could even be the front plateau.

Ok the only case where this might make sense is not while coasting but when entering the cutoff speed of allowed maximum speed of assist. When crossing this limit normally you got the resistance cut in or electronically regulated. With this you can bio-cycle over the max speed-assist without the annoying drag. !!

Still coasting you only really need doing mtb trails. Where a hub motor is not ça able of the torc and has to much weight in the rear.

What if traction is lost on the tire?

It is smart though.

No you’re wrong. We don’t want hub motors.

Unfortunately hub motors have the unavoidable problem of a dumbell effect. Having mass at the 2 farthest ends creates very poor handling. Move this same motor up to the bottom bracket and you'd have a winner.

Is there reason for keeping the outter most sheathing in line with the wires being swapped in harness? Why not remove the outter most sheathing entirely while moving the wires in and out of their places and through the narrow bore. Then when in place add it back to side of the harness that runs externally/outside of the motor to the circuit? Or alternatively leaving the old sheathing in place and using the old wires you’re being replaced to pull the new wires into the existing sheathing in a single motion/effort as opposed to fighting with both in both their respective directions in and out? I can’t imagine this is the easiest way to achieve the same results, and if so the motor company is on some bs frfr

nice

Anyone tried cutting the connector off the old wire and tapering the new wire to the external end of the old cable and either pulling the whole thing new and old through in conjunction with each other so as old one is pulled out from inside it would pull the new wires in from the outside. Even better probably Where possible, this could also be done while leaving the outer most sheath in place and connecting only the inner wires new and old to each other and then pulling the old out to also pull the new in of both the sheeth and the motor. So long as the wires being pulled in and out are continuous and connected in a way in which thickness constant and without large/abrupt variations , I’d think this would be a far easier option than fighting the twists and turns of the hard internal angels twice for the whole wad of both the new and old cable once to remove old and again to force new in…. Ntm leaving the sheath and using the old wires within to pull through new inner wires into the hub, could be done as each individual wire/smaller groupings of them (and thus more leeway with clearance for the hard part (ie passing through the case)) less thickness to be fighting with for clearance.

My race bike had a 0-5v pressure transducer screwed into a clutch master cylinder on the left handlebar. The variable wire was hooked up to the controller and modulated the regen function. Off throttle was configed with no engine brake so it free wheeled but 1 finger could trail brake into turns or even lock the rear wheel if I wanted. No planetary gears and the bike didnt have a rear disc or caliper for the 6 years I raced it.

while i personally wont be converting from mid drive to a hub motor, this should be making the decision infinitely harder for newcomers living in hilly country..

It's an example of my definition of intelligent design. A good design is simple, preferably simpler than what it replaces and better at performing what you are trying to do. Now I do have some thoughts on the generative braking. Unfortunately they make things more advanced and might not be real simple to accomplish, yet there are solutions that can be dropped in to solve most functions. What I'm talking about is something resembling a ABS system. Maximum braking and acceleration are generally when the tire just approaches the friction limit and almost starts sliding. While you can modulate the braking and acceleration manually it's not optional, and in panic situations humans tend to over react and mash that break to stop. With a sensor monitoring the vehicles speed over ground and comparing it to the rotational speed of the wheels it's easy to measure both of the wheel spins too fast or if it spins too slow and modulate acceleration or regen strength to match the actual speed and maximize braking or acceleration. Total wheel stop can be applied at something like half a meter per second to enable a final stop as soon as possible. Now I might be over thinking this, ABS systems in cars usually increase braking until the wheel stops, releases brakes and increase them again once the wheel turns. This is a simper idea and easy to implement, but it doesn't work when anti skid when accelerating is needed. Of all the equipment needed it's really only the sensor of ground speed that is new. All the rest are just programming to use the data to monitor the application of brake/regeneration and acceleration, and the computer capacity to handle these are so minimal it isn't a noticeable load on any current computer likely to be used in a system like this. Still I don't think it's simple enough to be a decent design idea.

we did not need that ai image...

Love this solution. As a mechanical engineer and Ebike enthusiast, good job! Justin I met you many years ago at a makerfaire. So glad there are people like you in the industry who care about the technology itself and not simply profits.

Really elegamt solution, looking forward to the shengyi sx release. Maybe you can start recommending/reselling front (suspension) fork with disc mounts and dropouts for use with this :D For the full battery case, does diverting the energy to the brakepads not also charge the battery up? (as it requires backwards torque, which during regen charges the battery) Would that still work when braking lightly? Would there be cases where the motor have to spin the brake rotor at a higher speed than the wheel to dump/not accept energy?

Seems perfect, I’ll definitely be watching for a new All Axle Rear with this tech.

Love the idea but plastic gears is a hard no from me.

Hiya Dude ...I'm not an mtber , mc mainly and RC. I was thinking about the additional Regen when the battery is at a high state of charge and if I got it correctly , the additional charge is dispersed as heat , I'm thinking could that be harnessed to a charge port for cellphone jumppack chargebank maintenance or better still an electicly heated coffee mug and siggybutt lighter ? .....and yes I don't get out much..... Super interesting video !!! 😉🙃😎 NZ

This is pretty brilliant, very very nice solution

I feel scammed because we were told it was for cars not bikes

Did china steal the idea and put it on temu yet?

I don't have hands on experience with planetary hub motor wheels, but in general, is spot welding a viable option to lessen possible damage? I'm picturing, if there's a clutch mechanism, there's most likely an overlap of some sort. Am I assuming correctly?

Those tolerances have to be tight. I wonder how right to repair is addressed?

a lot of ebmx bikes already have "regen" braking as a separate thumb throttle to use whenever you want. without all the extra crap this company is doing =/

This is really cool. One faliure omde you did not cover is what happens if the motor/contoller fails in an open ciecuit mode, say a cable is disslodged or cut somehow. Wouldnt that result in the motor more or less freewheeling, taking away alost all of the braking force?

Fabulous. And I have a question. Is there a reason it wouldn't work on both wheels? Is it because regen doesn't work well a 0 mph? A two wheel drive sounds a little like a race bike.

Its like orchestra!! A marvel! So happy!! Also---When can we pre-order, you need funding right??? Also, Imagine what you can do with more wheels!! like a recumbent bicycle. Thanks you

this is brilliant but I'm still a bit uneased by the lack of a real 100% mechanical brake in case of emergency with a partial electronic failure that doesn't allow regen nor stops the motor from spinnig

What is the point in spending an extra $X on regenerative braking just to save a fraction of X on the battery cost? Sure you could also cut the weight by a pound or two but how much is that really worth? You need to eliminate the mechanical brakes completely in order to make it worth it but that creates a safety issue. This all just seems like needless unjustifiable additional cost.

Chinese knock offs in 3....2....1.....

If it's going to be a while before this hits market, can you guys start selling kits first for conversions until then?

Ok. Take my money. Where/when can I buy it?

I had so many questions about this topic!

how sensitive are wheel speed sensors and hub motors to water intrusion? Do you have to avoid rain, puddles, streams, the beach?

Yeah, Toyota had a planetary based hybrid transmission on the first gen Prius.

Um and um and um and etc …. All the way through your talk your information was good but you don’t know know how to speak um and just drives people nuts plus obviously you haven’t done any serious E bike riding, on the hills that are a bit steep. You left out the number one need for regien !!riding in hilly country where you actually have to stop and let your brakes cool off if you don’t have regen!!! I know two overweight guysit have a horrible time going downhill. To me that’s the number one reason to haveregenand you didn’t even mention it.!!!

Obviously you don't hear the rear end in your vehicle, because gears are not square straight cut, they're angle cut to smoothly engage with more than one tooth engaged as they mesh. So major upgrade to these geared hubs have to be made, and they'll last ten times longer. Helical cut gears are the answer to wear and noise. Costing 4 times more. And I suspect a select few are done this way. Cheers

Am I missing something? The brakes are meant to be a safety device. This solution means no rear brakes at all if the electronics fail. Also, the maximum torque of an ebike motor is often 50 to 100Nm. You would need 5 or 10 times this for the brakes to work half decently for an emergency stop, or breaking at speed into a downhill corner. Why would anyone to throw away safety just to get an extra 5% of battery range?

That's fucking brilliant.

Whenever I see videos like this it makes me
