Thank you all for the compliments!
Absolutely AWESOME! I can't wait to get mine going! You need a solid R/C motor in that thing so it can really haul! How many watts are you pulling with that setup? I may have seen it but don't remember..
It has a 72Volt battery pack drawing 50 amps, so there is around 3600W going into the motor.
Just curious, what would you expect this bike to cost if you could build like 25 a year and still make it worth your time? Have you done a cost analysis?
We are considering producing a small quantity of these kind of bikes, and possibly a frame and swingarm kit that do-it-yourself types could finish with their choice of components.
If we use a chromoly frame we can make them for around $7500US.
That would be for a similar configuration to this one, and with many upgrades available such as a front hub motor for AWD, up to 30Ahr of battery capacity, and a built in charger.
We are working on a revised model based on what we have learned from this one. Carbon fiber is very expensive..and of course we can do that too, but it is much more labor intensive. I am most familiar fabricating with metal, it is easier to do in quantity and is much cheaper.
We can build a chromoly frame/swingarm kit for around $2300, nothing is set in stone yet though.
If anyone is interested PM me.
What is the max. speed you are seeing at 72volts?
It will do about 27/28mph or ~45kph right off the charger on flat ground, no pedaling, 200lb rider. It pulls hardest from around 10-20mph.
I can't even believe how cool that bike is! That ranks right up there with the Stealth Bomber in my opinion. Maybe even a bit cooler because of the carbon fiber. You really amazed me. A lot of people have ideas about building a bike like this but you actually saw the project through and that really impresses me. Good job!
More testing results..Here is a picture of the old planet gears and one way bearing, if you look closely you can see the crack in part of the bearing that was causing it to slip. There is only one that the picture shows, but there are actually 2 more cracks that are harder to see. The new one looks a lot stronger, it is all one piece in that area. I'll keep putting miles on it and we will see how it holds.
