What is the lifespan of an electric bike?

archa_pyus

Say you have an electric bicycle that is used daily, capable of a 30 mile range before needing re-fuelling and a speed range of 3-15mph.

What would be its likely lifespan, i.e. when would the whole thing have to be replaced?

I do not need exact measurements, just the general idea, as it is for a project for which i have to design an electric bike, which i know nothing about.

thank you!

Answer
The life span of an electric bike is mostly determined by the battery. Batteries can have a memory and if recharged before depleting it completely will reduce the capacity and can affect the range.

I would do some research on batteries. You can also look up motorized hubs to put on bikes, they make for the cleanest design.

Motors are rated in watts and most states have regulations that control the maximum amount of power that you can use.

how much does an 1200w electric bike cost if u charge it all day?

Q. an roomate of mine has an electric bike an the electric bill jump from 280$-420 is that possible

Answer
Hi, walker. The answer u wanted depends on the cost per unit kilowatt in your country. Because, electrical energy=w*t where w is the power consumed and t is the time in seconds. If you charge your bike a whole day,it consumes 1728 kwh. If your rate per unit is 1, you have to pay 1728 for it. If u were in india, rate per unit is Rs.0.75 and you will be paying Rs.1298 for it. Did i confuse you buddy? If u want more mail me at contact me.sundar@yahoo.in

Market size and growth scooters, electric scooters and E-bikes?

Paul L

Hi, I am desperate for help on this, I have spent many, many hours I cannot spare and am all searched out, I am desperate to find market details for unit sales (totals and growth rates) for Europe, China and Taiwan for gas powered scooters, electric scooters and e-bikes, also need USA figures for dirt bikes, I am trying to plug these figures into a very small part of my thesis and it sure seems no one will give this basic information unless I pay 3 grand or so to a market research company, it cannot be as hard as I am finding surely. I also need the details for reference on where the numbers came from.

Any help will be very much appreciated.

Best regards

Answer
you have two sources:
1- in the USA, check out the dirt bike magazines, they usually have the kind of info you are looking for
2- Out of the US, you have to call the marketing and sales departments for each manufacturer and ask your questions. Some of them post their numbers of their web sites
good luck

Ebikes, Electric bike motors, Electric scooters...?

Mantis

Anyone own one? Know what's good or bad? Where's the best place to buy? Pros and Cons?

Answer
Don't know much about scooters, but, know ebikes and ebike kits pretty well.

For DIY kits, Cyclone-USA has a great chain drive kit that gives the best range, top speed and hill climbing., but it is a difficult installation.

For value try a crystalyte kit, a hub motor which is always an easier install.
http://www.ebikes.ca/

For great features and reliability try Bionx kits.

A pretty nice prebuilt ebike is the Ezee series.

I am a support person for all of the above.

I personally own 7 ebike systems, including all of the above except for the EZee, which i get as a loaner.

for demanding applications, like tough terrain or heavy loads, got to have a chain drive cyclone. the variable gear ratio going thru your normal chain is really helpful.

But hub motors are an easier install.

Stay away from Lead batteries if you have hills to climb.

Some folks swear by the new Life04 batteries, I like NIMH, Nicad is showing very good value.

If you get an add on kit, out it on a quality comfort bike. No big box clunkers, they don't last the years of heavy high speed use.
