Electric Bikes - Putting motors on front and back of ezee quando

Hi, looking for some input...

I have an ezee quando II, which will go at most 15mph, and I am considering some modifications - specifically, getting a crystalyte hub (road runner or sparrow) for the front wheel, and keeping the motor in the rear that goes w/ the quando. Clearly, I would have two batteries going at once, and with a twist throttle already on the right handlebar, I would probably try to use a thumb throttle for the front wheel on the left handlebar.

Are there particular safety considerations I need to think of having two separate motors potentially going at a time? i.e. will the bike feel jerky, be stable, etc?

Also, if front and rear wheel are pushing at 15mph, does that necessarily mean that i'll be going 30mph?

thanks!

uh no

No, I'm really sorry, but it doesn't work like that.

As to the practicality of the whole setup I have grave doubts as to whether such a conversion has merit and would be worth even trying.

Dual motor setups have been talked about a bit before, you can dig up the old threads. Generally, the consensus is that there is an overwhelming addition of complexity, weight and rolling resistance for something you can simply achieve by increasing the power of a single motor, and that 15+15 does not = 30 when talking about dual motor setups.

You could definitely try contacting someone about increasing the current to your eZee, http://ebikes.ca (http://ebikes.ca/) has dealt with this motor, for instance. I'm not surprised its top speed is so low, considering the small wheels of the Quando II.
