new electric assist cycling technology

Hello,

we are investigating a new type of electric assist bicycle technology and are currently collecting the requirements. The project hyperbike.cc is a feasibility study contracted by the Austrian ministry for transport, technology and innovation. We invite you to help us to help you.
We would appreciate very much if you could fill in our on-line questionnaire at

http://www.hyperbike.cc/Vorlage.phtml?id=716

After answering tips about cycling are displayed.


many thanks for your time

best regards

I got into bicycle motors a bit recently.

At one point I ran some figures comparing gasoline and electric setups;
of the two (popular products) I compared, the electric cost over twice
as much and had a cost-per-mile that was five to ten times as high as
the gasoline engine setup. This was using U.S. fuel prices, Europe is
2-3X as high but still you can see the problem.

Advocates of electrics play yup the low-pollution aspects but that is
very debatable over the long term, considering the battery production
and disposal requirements.

There are a few situations where gasoline engines aren't practical--such
as when you desire silent operation, or for a physically-disabled rider
who wants "pushbutton power",,, but judged on a cost basis alone,
electrics still lose badly.

For longer trips around here, you can carry an electric bicycle on a
train but not a gasoline-powered one. It is primarily a safety issue:
you don't want passengers in a compartment with highly flamable
materials such as gasoline in case of a train accident.

If parking lots gave you free power up all day it would be cost efficient.
That is what they are doing now in the States. Not sure where but for a
parking lot company it would be a good idea.

Love this question
When riding an electric bicycle, what problem have you experienced most
often?




Unmantling of parts when driving

IC is subsidised widely by society, plus there are tons of small IC
motors around (economy of scale)

I'm all for making travel safe for bicycles and light electric
vehicles, which I believe can happily coexist on dedicated paths and
large shoulders on regular roads. It is a mistake though, to combine
electric and pedal power in the same vehicle. A decent cyclist doesn't
need the assist or added weight, and someone who wants electric power
doesn't need the extra complexity of hardware for pedaling.

A good electric scooter will weigh ~200lb and have a range of 30 miles
@ 30mph. No reason to put cranks and derailures an something like that.
And if you reduce the weight by making the batteries and motor smaller,
you might as well do away with power assist altogether.

One word here.
Solar!
Take a panel, even a fold up, and have a way to mount it when you are in
the building. Not for everywhere, since some thieve might actually
realize the panel costs more than most bikes, Treks excluded.

Tell us, how many miles does it go on one charge, how many discharge
cycles does the battery withstand before needing replacement, and how
much do replacement batteries cost (in US$)?....
