HI all,

Yes I agree to offer a complete bike.

I lower the price because I thought is would be the right thing to do while I have the wheels and batteries.

What's a good price for a basic E-trike?

The battery pack will cost about $1500.00 to build with new lithium cells for a 2000kwh bank with charging circuit.

Is $3000.00+ a good price for a lower range like 25 miles?

I can't change the asking amount but could add the $3000 -$4000 for a complete E-Trike R1 and R2 models.

Sounds about right for a specialized bike. There are ebikes going for 10,000 and up out there. 55mph for 50mi.  You should be able to get more than 25mi with that pack.  The 1kw motor may be an issue. 750w and under is street legal in all 50 states. 1kw can get you 30mph or better, but 20mph is street legal in all 50 states also.  My trek has a 500w 48v and it can do 25mph with 26in 2.0 tires.  And a 500w motor kit is cheaper. ;)

My bike is about 80lb with 14ah sla(4 of them) and Im 225lb. And it will peel out from a stop with full throttle.  Love that bike. I get over 20mi, with stops and goes along the way, where most kits are mile rated for no stops, just full throttle on a flat road. So with the 12ah, I would get less than 20mi with stops and goes as it was rated for 20mi, no stops. Its the acceleration from a stop that uses the most power. Best eff is at top speed.

But many people are riding around at 35mph and nobody(yet) has issues with cops.  Many police dont even know the law when it comes to ebikes. Sometimes they may say, "hey, you cant ride that on the sidewalk". But if it is within the limits of the law as I have posted, and it has pedals, it is a 'bicycle" period.  Just be nice with them and explain and it shouldnt be an issue once they understand.

But if they start cracking down, since there are more and more of them riding around, the power and speed will be a concern. You can use a resistor network on the throttle output to the controller to lower the top speed in your case. And have a turbo button to climb hills and such. ;)

The reason I was saying to ask for more is, you will need more funds to build more bikes. And the more funds you have to start with, the more parts you can buy in bulk and build the bikes cheaper. More profits, or happier customers, which ever you decide upon.

So, you can do another pledge drive after you finish this one and its a proven product. No biggy.  But it would be nice to just go for it, ya know? ;D

Keep up the good work. And best of luck. ;D

And if things go well, check out Alibaba.com to source your kits and batts. Some of the companies will sell singles, and others want a quantity buy in. Thats where the ebay sellers are getting them. ;)

Hi Mag,

Thanks for the input.

This is a test design look before I start doing welding on the front end a-frame and steering.

Hi Telecom,

Yes, I plan to do a derailer also.

I am looking at a air ride shocks, I can make them cheaper then spring shocks.

Tomorrow I plan to work on the front end.
