Nope, but I just bought in on kickstarter for the Urbanx wheel (front wheel version). Reasonably priced, ends Monday morning. https://www.kickstarter.com/projects...ric-bike-in-60 don't know if it meets your needs....

I ride to burn calories so I can drink more beer. 1,500 bucks buys a lot of beer that I wouldn't be able to drink because I will burn less calories riding.

Seriously, I have a feeling that I will be in the market for e-assist in 15 years or so. With developments in battery technology and increased demand, value for the price may be darn good by then.

Might not be too bad in the wind. When I got a set of grocery panniers in 2015 the first thing I did was take 'em empty on a ride on the hilliest, windiest route around on a day with steady crosswinds and gusts up to 20 mph. Wasn't nearly as bad as I'd expected.

Anyone who has one would have to be a 'true believer'. They are only now shipping a few of these wheels to folks that ordered them in 2013.

The company is apparently involved in a couple of lawsuits and there are 'net claims they delete complaints on their comment page.

There are plenty of competing products that one can walk into a B&M, try and buy.

I'd consider one for fun if they'd up the speed limit to 45kph like some other bikes. Could shave a few minutes off my commute. People seem reasonably pleased on their Facebook page but the battery life seems it might be less than originally planned.

So it was bad.

I've been reading about this product for nearly five years. I've never seen one. I'd love to try one. In the meantime, I'll continue to commute on my ebike.

I tried one this afternoon at the NY Bike Jumble.

It was awesome but very heavy, and they are not cheap. I want one!

I borrowed one for a couple days a few weeks ago. Used it commuting to and from work. I'm sure it's not for everyone but it's just what I've been looking for. Very smooth and powerful and has enough juice to assist on my 62km round trip. It saves about 10 min each way off my ride and smooths out the intensity so I don't have to push so hard on the hills. I plan to use a couple of times a week when I need a break.

The regenerative braking is also a great feature which applies a strong braking force when you pedal backwards slightly. The max speed is adjustable up to 40kph. It would be quite usable for me with a single speed bike so that may be my next acquisition.

I ordered one and it should arrive tomorrow.

How efficent is the drivetrain when pedalling? From the pics on their site it seems to have a clutch like mechanism - not the most efficient in terms of mechanical losses (at least when you have a low powered human engine at disposal). The spoke system also looks strange - not sure about spoke replacement and the wheel's strength/durability.

Compared to other electrical bicycle systems, the main advantage (and selling point) seems to be the universality - any bike can be fitted with such wheel, even if the frame is not designed to take up bateries - fitting out of the box, without the need to manually adjust your bicycle.

I also wonder how long the bateries last.

When these hit the news 4 or 5 years ago, I read that they were individually replaceable 18650 cells. That might have changed by now, but they have 300-500 full charge cycles before the capacity drops some 30% or so, double those cycles if you have a more reasonable charging with something less than full cycle. Roughly speaking.

The price is also double what was published back then, priced out of what I'd personally be willing to pay. Still, if you want the battery you've got to pay, and it's tempting tech. I'd like to have one.

Pretty difficult for me to measure efficiency since I don't have an accurate way to measure how much power the motor is adding. I'll ride it this week with a powermeter but that will just tell my my effort. In any case, it works very smoothly.

I wanted a drop bar bike that wasn't too heavy. There aren't many drop-bar ebikes under 40 lbs.

Battery is relatively small, 280Wh, but big enough for my commute and that's all I'll ever use it for. I wouldn't normally use the e-bike on a ride.

Definitely not individually replaceable cells. That wouldn't work well. They claim 1000 cycles to 70%, we'll see. If I have access to the battery through the charging port I may measure the capacity at the beginning and keep track over time.

I'm curious about the non-assisted mode. When assist is off, does it take noticeably more effort to ride on flats and up hills, than with a regular wheel?

It certainly doesn't accelerate well when there's no assist and it feels like it's actually applying brakes but when I look down at the speed and consider my effort it seems reasonable. When I borrowed the wheel I didn't have a powermeter on my bike so it was a little hard to tell but I suspect it feels sluggish because it's a 16lb wheel. I set the max speed to 32kph one morning and didn't have any problem averaging 35 with a little tailwind on a 30min section of highway.

Going up hills I expect to be about 8% slower due to the weight. I have a bridge about 60m that took 3:34 to climb this morning. With an extra 16lbs it should take an additional 18 Seconds so not a big deal. With the wheel assisting the climb took 2:20.
