How are motorized fat tire bikes?how is it on pavement?.
do you have any suggested bikes .or better bikes that I could go with for all year round use
I consider Fat Tire bikes anything with tires wider than the 2.25" Balloon tires on big beach cruisers.
I find 3" tires with non-aggressive tread to be most comfortable to ride and manage and 4" off road tires like this to be just a bit too much for road use.
Beside being a bit much for road tires you can's fit squat in that center cavity but a big battery, in the this case a 1KW 48V LI and 1.8KW electric motor.
Regardless of power source you are going to want to resign yourself to using the bikes right side drive to power the back wheel and not a new sprocket on the left for direct drive.
That being the case you want a bike with a geared rear hub and good brakes already on it.
The Sun Crusher with 3" tires is good bike with dual V-brakes, 7-speed and a huge cavity big enough for even a big 4-stroke engine but this one is a legal 48cc with and expansion chamber and shift kit and a real joy to ride.
The Micargi Slugo is a pretty decent 7-speed with dual disc brakes.
It will take a 2-stroke and 4-stroke as well.
My latest fat tire fancy is the Fito Molena.
So much so there is a new Grube GT2A in-tank frame based on the Fitos wheels and brakes in the works.
It will take a 2-stroke and 4-stroke as well.
Imagine this with the top tube being a 1/2 gallon gas tank.
That 4-stroke shifter is the first 10G KCK shifter.
As mentioned above, flats are a concern so you always want to put a good tire liner between your inner tire and outer tube.
As far as road handling 3" rocks, especially with those Fito 3" Flame tires and HD Kenda tubes that come inside.
You can feel the meat on the road in turns and running them with about #25 of air they really take a lot of the road out.
Those are the basics, good luck on your build as some parts can be pretty challenging, but then again that is fun part, especially if you have a bunch of spare parts laying around ;-}
