First I've heard of it.
Could be the real deal, I suppose.
But with a 120W motor and a 14.4V, 11Ah Li-ion battery (basically a big laptop battery), I can't quite see where they get a range of 25+ km (15 miles)... unles you do a whole lot of pedalling. Enough pedalling that the contribution from the motor is negligible.

Well, I can't imagine being very comfy on a bike like that for very far anyway. The small watts is going through an interesting concept for the motor though. I suspect we will see more of this kind of thing as RC motors take over ebikes. Almost a front hub stokemonkey. Sorta Frankenbike cool.

Just in time for Christmas 2010, the New Razor E100! ...
well, nearly.
This looks like the next step in the evolution of those razor scooters. first came roller blades on folding sticks, then came electric rollerblades on folding sticks, then seats, then bigger wheels, then better motors (e200, e300..) then better seats, then better wheels, and now even better seats, wheels, and a novel new motor!
Lame, but I might just buy one for my nephue.

I've just received a very small folder with integrated batteries. It's not quite as light as this but has a proper 250W hub motor and 24V Li-ion batteries integrated into the frame. Not sure of the capacity but believe it's about 6 or 7Ah. Will confirm later. It does about 15mph and has a reasonable range. Weighs 14kgs all up and even comes with a carry strap and a custom bag to hold it which neatly folds up into a ruck sack.
The motor is a small high rpm geared hubmotor rated for 250W and tyres are 12.5" * 2.5". I've only just received it and I'm really impressed with the whole package. Very nicely done and functions very well. I'm thinking an additional input for a small extra pack and you could extend the range a bit, maybe even a bit more speed with a 36V pack

I'd guess you have to take the forks off to get to the battery in the main tube. That's a novel drive and looks to use a pancake or printed motor similar to those found on goldenmotor.com.
That would be a great parking lot bike for Arizona. The big trick to keeping comfortable in Phoenix was keeping your core temperature down, but the walk through a big parking lot was enough to get you heated up. One of these would be perfect for dashing between air-conditioned locations.

What brand is the bike? Do you have a link? I'm looking for a front wheel hub motor to fit my Mobiky Genius. 12" tires. Perhaps this would work. Thanks.
It's not retailed. I got it as a sample and am thinking about exporting them. The case of the motor looks exactly the same as the Cute motors but it must have different gears as it spins very fast at only 24V. A 24V high speed cute motor should have more than enough rpm for even a very small wheel if you over volt it to 36V. They're about 290rpm at 24V, so over 400rpm at 36V. The ananda motor also comes in a smaller 85 package which should be possible to order with differnt axle to bring dropout size down to 90mm or maybe a bit less.
Neat bike. Please let me know it you decide to get involved. I live just outside New York City and it looks like a great bike for a commute, especially if it folds. Its really light too. Be great to get it up to 20mph though.
Lynchy, I have a Mobiky Genius with 12" wheels. Any thoughts where I might get a front wheel hub motor. Again, Let me know when and how much your bike will be. Thanks.

Poz12,
Yeah it is a neat little bike. I've put a bike computer on it today and the freewheel rpm is about 460rpm which is about 27kph. Might be ok for 20mph with a 36V pack but that wouldn't fit in the frame as is. Will run it to school in the morning and see what it does. Drop me a PM, we can have a chat
It's late here now so I'm off to bed.
I've got another motor here that might have sufficient rpm for such a small rim if over volted. Will let you know.

On the way to school and back it would do about 22-23kph (approx 14mph). Bearing in mind I'm 90kgs, plus a rucksack. A smaller guy at school tried it, he's about 55 kgs and he reckoned it hit 24kph. I reckon the motor is only about 180W and although it accelerates quite strongly initially, it is a little slow if you're going any kind of distance.
I've taken the battery and controller out of the frame today. The battery is tiny. Looks like Li Polymer. Weighs 715gms, has 7s, 2p cells with BMS. Gonna put it on a load when I get a chance and see what capacity it's got. It's claimed 24V 6Ah. There's a few things I'm gonna change and I reckon you could get a bit more Li Pol in there too.
I fitted a nice little 36V 6Ah LiFePO4 (2.7kg) pack to it to see what it does. The standard controller has 50V caps and it seems to be holding out just fine. It pulled 20mph with fresh batteries and 19mph after it had settled down. It's really torquey and is pulling over 500rpm at 20mph Goes really well, I'm really impressed with it. Gonna take apart a 36V 9Ah LiFePO4 Pack I've got here and re package the 26650 cells to fit behing the bottom bracket. Might stick with 36V 6Ah to keep the weight down (approx 2.5kg). Maybe put a 3 speed internal gear on it too, as even though it's got a really big chainwheel, it's still quite short geared.
Also need to crack open the motor to see how they've managed to get those crazy RPMs. It' looks like a Cute Ananda motor. It does no load, 666rpm
at 36V
I reckon these micro e bikes are the future. 15kgs, folds in less than a minute, 20mph and about 10 mile range without pedalling (to be confirmed). Can bring it on the subway and so easy to bring up stairs as it's so small and light. You want to go a bit further just throw a bigger battery at it.
