    Could This One Be Motorized

    Just purchased a rare chainless bike with an enclosed shaft transferring power from pedals to the 7 speed Nexus rear wheel hub. Now wondering what to do with it after doing repairs? Looks to be top quality construction but can find nothing on date, manufacturer, or history on the Internet. Any...

    Fat Tire Folding Bikes

    With the warm weather drawing to an end I put away my gas/electric bikes and bought myself a bike for the coming snowy season. The fat 4 inch wide tires on this bike are inflated to 65 psi to minimize rolling resistance but I am planning to reduce that by quite a bit and use the bike for biking...

    Does The 2 Stroke Motorized Bike Spew Blue Smoke

    Since I ride alone I always wondered if at 30 to 1 mixture, does my 2 stroke motorized bike leave a trail of blue smoke. Ever since I discovered motorized bicycles I saw them as a fun set of wheels for old guys who will eventually loose their drivers license. From the outset I realized that it...

    Adding Gears to Phatmoto Rover II

    Are there any Phatmoto owners here? I have been gathering parts for one of my pet projects; adding gears to the pedal system.

    What is your sweet spot motorized bicycle speed ?

    Today there was no one around so I took the opportunity to do some engine runs and test just how fast I wanted to go on my Schwinn Beach Cruiser Hybrid.

    Bike inspection before riding

    Just finished reading a post by a well known Phatmoto owner reporting on a Brake Disc screw that popped out and grounded him for a while. His advice is to check of your bike before each ride for loose nuts and bolts, something which I strongly endorse after my most recent experience. With this...

    2020 Phatmoto Rover Choke Position Labeling Error

    I have been riding my Rover II for a couple of weeks not knowing that I was riding with the choke in the wrong position. It wasn't until I complained about the bike's performance did an observant viewer notice I was setting the choke position to OFF when I was about to begin my ride. Maybe I am...

    My first attempt at trying to create a Gas/Electric/Push hybrid bicycle, gas power when I am alone on the trails and need a thrill, electric on crowed paths and pedals on the level or down hill grades.
