Doublewhiz - Twin Engine Whizzer Motorized Bicycle
July 27th, 2008 by Paul Crowe - "The Kneeslider"
For all of you small displacement, lightweight motorcycle guys, here’s something I came across as I wandered around Vintage Days 2008 at Mid Ohio. It’s called Doublewhiz for the twin engines it currently sports. Total displacement is 276cc. The engines are Whizzers, or whoever made them for Whizzer, and power runs through a 3 speed transmission. I’m not sure of the year this modified bike is based on but it is pretty cool. Just shows how a custom builder will start modifying just about anything for a bit more performance so no matter how anemic some future vehicle might be, some guy will always look at it and start to wonder, “What if …?” and the process begins.
Whizzer has been making motorized bicycles since 1939 but the company has changed hands and gone out of and back into production over the years but they still retain the motorized bicycle form of the originals. Current models are 138cc with a top speed of 25 mph.
I don’t know if this is any kind of daily rider but I bet it has enough performance to get this guy wherever he needs to go for short trips and errands, maybe even back and forth to work. It’s certainly as practical as some of the first electric motorcycles being built and it probably has a much greater range. Interesting.

Looks like a good start to a V-4…

Put some clubman bars on it I’m there . :)That’s more interesting than a Kymco scooter and style to boot !

Looks like it would be lots of fun to ride, I’d love to see what the performance specs are.

Believe it or not, there is a Whizzer club in the OC, where I live. They often rally on down to Huntington Beach, where I live. These bikes are immaculately maintained. Judging from the trail of broken down bikes they leave strung out along their path, daily driver is not a category they fit into. Doubling up on engines is going to only make downtime more likely.

The frame looks awesome.. and completely custom. The down tube splits into two and looks like it was taken from an old bicycle. same with the seat post.

Putting an engine, especially 276cc of engine, on a bicycle is asking for trouble. The specific power output may be low, but bicycle brakes and suspensions are usually not designed for speed like that motor could dish out. At least this example appears to have springer forks; I hope they’re functional.
Most Whizzers are basically ultra-light flat trackers. Fun, I’ll bet. Practical, not a chance.
By the way, if this bike can run on a single engine then it actually has a much better chance of making it home without a breakdown. It’s design for redundancy!

Ive seen lots of cheap Chinese clone engines for sale out there, but havent heard much good of them. The motorized bicycle area always seems like an answer to a question that was misspoken.
Interesting mod, I would like to see how both of them are setup to react with each other.

With all the attention, maybe next year he will have a triple. Then he could “whiz, whiz, whiz” on a “Super Whizzer”

My first real motor cycle was a Whizzer. I moved on to a BSA 500cc Royal Star and Suzuki’s.
