All Wheel Drive - with a mid drive ?

[Deleted member 4210]

Well this is an interesting beast...neither wheel has a motor built in.

Christini's Fat E-5 features a 1,000-watt motor, 50 miles of range, 4.8-inch-wide tires, and a hidden mechanism that will enlist the front wheel to get you through the snow.

Interesting bike... not sure about the long term reliability and durability of the front fork gear drive.

I’m Overdoing it with my likeness for the BH brand but I saw one of this in reality and is very sleek looking.

I found more technical information on the Christini AWD system... both front and rear wheels are gear driven.

No way those small dry gears will last long. Just because you can do this doesn't mean it's a good idea. A better configuration is a simple two wheel drive bike with a front hub motor (either with a mid drive or just the rider powering the rear).

I think this is a solution to a problem that people for the most part don't really need solved.

In all my years of riding I think the only time this would have been useful would be steep mountain bike trails. Other than that I can't see that this is something I would want/need. Maybe some marginal benefit in other situations but not enough to justify the complexity and expense.

I agree this is a very narrow market bike... the only other use case would be deep snow or sand.

That should receive many engineering design awards. Amazing system.

Sand would be brutal on those open polymer gears and sliding spine on the suspension fork drive!!!!!! No fenders even makes it worse!
