I am an older guy that wants to ride a bike for exercise on the days I dont golf. I also wanted alternative transportation to my 'dinghy' when out on the road in our RV. I have a bike rack that fits into the trailer hitch mount on my 'dinghy'.
My bike is a PHAT CYCLE cruiser with one speed and coaster brakes. I have fitted it with an front fork brushless SLA rechargable battery powered electric motor to assist on the hills. (takes the place of multiple speeds). On the flat it will do 20-25 mph for 20 to 30 miles. Of course when pedal assisted it will go further. I am also fitting it with a cargo trailer to carry stuff from the store and golf clubs when needed.
I like the idea that it recharges for pennies from any outlet.
