Electric motor for bike?

Q. I have a recumbent bike - E-Z Sport. I am looking for an electric motor for it - for a good price. The best I can find is an E4 for $700. Can anyone help me find a better deal? I love biking but have become disabled and need a motor in order to contine biking with family.
I can't use a moped on bike trails. I want to continue biking with my family on bike trails.


Answer
I assume your U.S. have a look at this kit. The motor is very efficient (>95%). This will give you the best range out of what ever batteries you choose.

You can buy the kit or just the motor/gearbox.

Being a recumbent you should be able to mount the motor near your idler pulley and keep your original chainrings. The down side to this method will be that you need to pedal when the motor is on. Depending on your disability you may wish to go with the freewheeling chainring that they supply with the kit.

A front hub motor will not work so well on a recumbent (not enough weight on the wheel)

I want to make my bike electric and I don't have a clue where to get the supplies and how much it costs to get the supplies. I want to make my mountain bike into an electric one.

I'll give you a hint: Hub motors have some disadvantages compared to motors that drive the bicycles chain, namely low speed thrust for climbing steep hills with heavy loads. But that never actually becomes a factor because your speed never drops too far when you ride an electric bike. The good outweighs the bad when it comes to hub motors.

I recommend Crystalyte 5000 series hub motors. And absolutely pay a little extra and get lithium batteries. The lighter weight means longer range and better performance, and they pay for themselves in the long run because they have a longer life span.

It's going to cost you some money if you want the best quality. If you don't like the sticker shock, walmart sells an electric bicycle you can search for on their website. It's dirt cheap and it will last a few years if you take care of it.
