## EV World publisher seeking to Kickstart e-bike project; EcoForce bamboo/aluminum bike with Bike+ All-in-One hub as incentive

##### 24 July 2015

Bill Moore, the publisher of EV World and longtime electric bike enthusiast, has spunoff a company, QuikByke, that will rent top-quality electric bicycles in tourist markets on a seasonal cycle: winter in the tropics, summer in the north. The e-bikes are housed in mobile solar-powered rental shops based on 20 ft shipping containers (called Q•pods), each with 15 bikes. Moore is seeking $275,000 in crowdsourced funding by 14 August to build Q•pod #1. As an incentive for supporters, QuikByke is offering the K15, a Greenstar Bikes Ecoforce 1 bamboo and recycled aluminum e-bike powered by the BIKE+ All-In-One hub motor by Zehus s.r.l. of Milan, Italy. The BIKE+ rear bike hub contains brushless motor, 160 Wh battery, electronics and sensors, all within 180 mm diameter and 120 mm width. With a weight of just 3 kg (6.6 lbs), BIKE+ All-In-One has the highest energy/weight ratio on the market. At just over 31 pounds (less than 15 kg), the K15 (hence the name), including motor, is among the lightest electric bicycles. QuikByke is offering a signed, limited pre-production run of 150 of the K15 bikes for an investment of US$1,975.

Very clever idea, I wish Bill the best. 160 Wh will not get you very far though, even on a bike.

he ZeHus BIKE+ motor algorithm is designed to work more like the Toyota Prius than the Chevy Volt. The ZeHus App offers 8 assistance levels, In the BIKE+ mode the battery recharges itself and you never need to plugin to recharge. The further to the left you slide the smartphone setting in the App, the more assistance and, of course, the quicker you drain the battery. This bike is intended to fill niche between a standard bicycle and a traditional e-bike with 350-400W/h battery. And at less than 32 lbs., it is among the lightest electric bicycles available. It's bamboo frame and recycled 6160 aluminum gussets also make it among the most sustainable.

Check out the impromptu endorsement Nagesh Rao, the chief technologist at the SBA's Office of Investment and Innovation, gave the bike last week during the SBIR Road Tour stop in Lincoln.

I think he has over-innovated.
Bike rentals are a good idea.
E-bike rentals are a good idea (but the bikes cost more).
HE-bike rentals are a good idea (ditto).
Bamboo HE-bike rentals are also a good idea (ditto).
Solar charged Bamboo HE bike rentals are also a good idea (ditto).

I think he has increased the cost of the system to an unreasonable level and is likely to fail as a result, which is a shame as Bill is a good guy and is trying to do the right thing. He just needs an accountant on his team.

I would like to see a normal (non-bamboo) bike with that wheel in it, or better still a CF framed one.

IMO, there is no need to have mixed aluminium/bamboo frames in a bike, just stick to a single material to keep it simple and easy to manufacture. Aluminium is already easy to recycle so there is not a "resource depletion" problem with any bike.

As ECI says, a few more Wh in the hub wouldn't hurt, but if it is a hybrid (rather then a PHEb) then it shouldn't be a problem.

But still, push it up to 300 Wh with the next version.

A 14 Wh 18650 cell weighs about 54 gm, so an extra 140 Wh would only weigh 540 gms (although it would need a bigger hub).

We just finished three solid months of research on virtually every electric bike made. The result, with a full page write-up on each of our top 32 picks out of over 100, was just sent to the printer and will be on newsstand sales in a couple of weeks. The matrix page lists a comparison of battery and motor specs. The lowest on the list is 288 Wh. The highest on the list is 1,920 Wh (admittedly a lot, more than most electric mopeds, which we also cover).

So 160 Wh is about half that of the bottom tier, and one third that of the mainstream commuters. Very light vehicles like bikes don't do all that well with regeneration. Speeds are low, and there's not a lot of mass (less kinetic energy recovery potential).

I love the idea of introducing a lot of people to electric bikes through rentals. But if it's a substandard experience, it will be not only ineffective, but possibly counterproductive.

The Zehus will get you off the line with less effort, but it won't flatten grades, something electric bikes usually excel at. If Quickbykes are used at the beach, on the boardwalk, this might not be a problem at all. But it also won't do much more than a normal bike would do.

They will be easier to administer as rentals, since the Zehus does not require, or allow, charging from wall sockets.

But hopefully Quickbykes will expand the line to introduce people to the real power, and capability, of electric bikes.

I'll support the campaign. But I agree with mahonj that the price tag seems really high for such a simple operation. Hopefully they get that in line after the first MVP.

@ECI
What will the e-bike publication be called.
Is it linked to any websites - any chance of getting a preview of it ?

It's called Electric Car Insider magazine. We lead with print, it's on the shelf at Barnes & Noble and Hastings in the U.S., Chapters/Indigo in Canada and several hundred independents through Ingram Periodicals and Newsways. We'll have a new redesigned digital tablet edition on the Apple Newsstand and Google Play within a month. We'll have more info on the ECI web site within the next week, where we also sell mail subscriptions.

I'm hoping Bill's campaign is a big success, it will make an interesting story. A lot of innovation there. Looking forward to hearing more about which north/south locations the container will land in. I'm a snow bird myself.

Electric cars solve the local pollution problem in cities, but they don't solve the congestion problem as they take up as much space as a normal car.
Electric bikes and scooters solve the congestion problem and also the global pollution problem as their energy requirements are so low.
The have advantages over push bikes in hot countries (less sweat) and have a longer range for moderately fit people.
Pedal assist bikes give some exercise, but not as much as pure push bikes.
The only problems I can see are safety, bad weather and lack of prestige. (You don't really want to roll up for a big meeting and sling your bicycle helmet on the boardroom table).

However, for many situations, they are ideal commuting tools for trips of < 10 miles.
