how do i get electric bike to spin the chain?

csmuch41

i wanted to make an electric bike but i dont know how to make the chain spin... how does it work?

does electricity and battery make it spin or what how does this all work?

Answer
You are right. An electric motor and battery are what is needed.

But most electric motors are either direct drive in the rear hub OR there is a roller that drives the front wheel directly. With your level of expertise I'd recommend getting a kit. Australia do some good ones.

a standalone modular low cost electric motor set for existing bicycles?

thehighlan

I am from India ..and we sell abt 10 Million Bicycles in India every year

I am looking for a low cost modular motor kit..which can be charged by simply plugging in to the AC mains..and can be attached to our bicycles by simple tools..nothing too complicated is gonna work here


i searched online and found one or two products..but they were prohibitively expensive


is there ne one out there who can help me

thanx in advance

Answer
There are a wide variety of electric bike kits available. Most include hub motors which are pre-installed on a rear or front wheel. You simply install the wheel, run the wiring along the bike to a controller and battery, and you're all set. Here are a few of the different options available:

On average, you can expect to pay between $300-$400 for an electric bike kit (without battery). Then batteries will vary depending on the battery type, but can cost from $125 -$500+

What is the lifespan of an electric bike?

best electric bike hub motor image

Q. 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 can I figure out how fast my electric bike would go?

morbeckbra

I'm trying to put together an electric bike, with parts from http://www.electricscooterparts.com/. I'm using a standard bike frame that weighs about 30 pounds. How can I calculate how fast a hypothetical electric powered bike will go just from looking at the voltages and amperages of the batteries/motors listed on the website?

Answer
wrong data. you need motor rpm and drive train ratios. voltage and amperage gives you power, watts or horsepower. which will let you figure how long it will take to get to top speed.

example: a hub motor with no gears, running at 250 rpm will move a 26 inch bike wheel at about 20 mph.

Can the pedaling energy charge the battery of an electric bike?

best electric bike hub motor image

Drowzzy

Can the mechanical energy of pedaling be stored as electrical energy to be utilized later to run the bicycle automatically? I'm not talking about pure electric bikes that need regular charging, and not even about those that you pedal for a while as the bike stands still and then run it on electric power. I mean can you ride a bike and store the mechanical energy simultaneously? Will it be efficient? If so, then are such e-bikes available in the market, and what are they called so that I may Google for them?

Here's the scenario: I need a bicycle for regular commute, may be even for covering long distances. It's not feasible for a layman to pedal continuously for more than 5 to 10 miles. So I'm looking for a bike that you pedal for sometime, and when you're exhausted, you simply flick a button to make it run on electrical power which has been converted and stored from the mechanical energy of pedaling the bike; and then pedal again and auto-ride again and so forth. Will something like that be technically efficient, since you're moving the bike while pedaling as well as storing your spare energy?

Hope I haven't confused you. Thanks :)

Answer
There is already such a motor on the market. The name escapes me right now but it is a hub built into the rear wheel and it costs about $2000... not the Erbike hub motor... I think it is Electricrider or something like that.

To your request, yes, it is possible and a project I am working on right now. No, I can't and won't divulge details but CAN tell you that you'll see it relatively soon and it WILL be expensive- more expensive than a small motorcycle at this point.

By the way... I typically commute 24 miles (one way) to work on a bicycle, no problem. 5-10 mile commute is simple for most committed riders.

I'm looking for a CVT or IVT transmission for a diy electric bicycle?

Joel

I'm planning out a DIY electric bike, and I want to use a direct drive system. I'm thinking about using a couple angle grinder gear boxes instead of chains and gears, but I need a CVT or IVT transmission. That's Continuous Variable Transmission or Infinite Variable Transmission.
It would be great if there is a power tool or some other low-cost component I could dismantle to easily get one of these transmissions. Go Karts use them, and they are cheaper than I would spend at a bike shop, but they're built really beefy for the kind of strain a Go Kart motor would put on it. Does anyone have a suggestion?

Answer
i have built my own elec bicycle .. i used a " hub motor bicycle kit . total cost of $230 for the kit including charger . throttle , and controller box Then you have to buy the batteries separate or you can buy " chain driven elec bicycle kits " you dont need transmissions using DC elec motors because they ae Variable speed motors . the " throttle " controls the speed. The higher the voltage of system the faster it will go. mine is 36 volt. 500 watt. with 6 - 12 volt 12 amp hour batts to make 2 -36 volt battery banks. next time i will try a 48 volt 1000 kit.

also google " electric bicycle youtube " and " elec bike forums " to learn more. Hub motors are much more efficient and quiter too. .

I want to convert my bike to an electric bike, anyone have any experience with this?

Q. I want to convert my current bike to an electric bike for less than $200. I'm really not that handy with electronics, but if some instruction to put A into B I can do it, I just wouldn't be able to figure out that A goes into B with out the instructions. Anyways, does anyone have some tips? All the sites that I've found are very unprofessional or non-specific so it's really hard to figure out anything from them. I would be willing to buy a kit.

Answer
An electric bike has to have a motor, controller, throttle, and battery pack.
Hub motors are the easiest to install.
overview:
You remove your old front wheel, put the new wheel where the old one was, align the wheel in the slots, adjust the brakes, secure the controller and the battery pack on the rear rack, put the throttle on the handle bars, route the wires safely and tie-wrap, connect the connectors together, turn every thing on and test.

To be of much use, you have to have at least 250watts, and hopefully more.

Largo scooters has a decent kit (go Hub)for $600 and is nice. Every once in a while you can find a WE or BD36 for maybe $350.

A Largo kit has keyed connectors so you cannot hook it up wrong.
