Really neat but the price is a no-go. For US$3,985 you can get a really, really, really good conventional bike that you can really ride.
Now if the Yikebike was US$398 then sure that would be worth it. The price is for rich people with two much money that want to impress their friends with their coolness.

Yeah, you can convert a regular bicycle to run at those speeds at that range for a 10th of what this costs.

too expensive to be anything but a rich person's toy, too dangerous to ride for real.

Why no images showing this bike being ridden?

The problem with electricbikes and cars, is that every one thinks that they have the answer we have been waiting for. They (builders) want to make a billion dollars for $10 worth of inovation. If you went to India with a set of drawings they will tell you it can be made and then ask you what price you want to pay and will build to that price. I would buy one for around $150 $200. Same with electric cars. No motor no gear box no dif, just electric motors in the wheels I'd buy one for $5000. The idea of paying for nonexistent parts is why the idea has not taken off. Its all to do with "Priced at what the market will bear".

I have to agree with the commenters. What economy are you living in? Throw in an inexpensive solar charger and an extra battery for quick changing. Better yet, a foldable solar charger in a side bag. Then, maybe the cost would be justified.

@ pointyup....you would pay $5K for a regular bike with motor in the hub? wo0wser, I guess I am aiming too low. I want to build a 2 seater with lugage room for that price. Maybe I should get some more zeeros lined up?

"Yikebike" must be technospeak for "faceplant".

Is not present bike versatile,time tested and cost effective?

@Walt Stawicki, About how long from now are you planning to go into production? What are you planning to do for the battery? Please reply to MarkLRoest(at)gmail(dot)com
