Remember the old Whizzer motorized bicycles from the 1950s? Ever wonder what they might have evolved into with modern technology applied to this inexpensive form of transportation/ fun vehicle? Well, back in 2011, with gas prices always going ever higher and the economy in the tank, Dave Rush found an inexpensive way to have fun and go racing.

Dave Rust, owner of Arrow Motorized Cycles, with three of his creations after some dirt-track racing at California’s Perris Raceway. Rust has a Class C background in motorcycle racing. He rode for Shell Racing at one point in his career, but now he helps the kids in the neighborhood – and anyone else who wants to experience two-wheeled fun – find an inexpensive way to participate.

Coming from a flat-track racing background, Dave knew all too well how much money was needed to fund a solid racing program. But what about the guys or ladies who just wanted to race for fun, or even just ride for fun?

Dave found a Russian-designed, Chinese-built two-stroke engine made for attachment to bicycles. At first, Dave developed and tested his own reed boxes for these engines (which come in three different displacement sizes). Then he and his brother Jim attended a local race just for motorized bicycles. Suddenly Dave realized there were enough enthusiasts out there for him to market his reed box, as there was nothing available in the industry to enhance the performance of these 100-plus-mile-per-gallon bikes.

So it was that in 2012 Dave launched Arrow Motorized Cycles, offering reed-box kits, exhaust pipes, performance cylinders and heads, along with spare parts and some smaller items from his newly created website.

The drive train on the Arrow uses Shimano hubs, with the rear-gear cluster by Shimano as well. The chain is a standard number 420.

For publicity, Dave created a three-bike race team using neighborhood kids. They started racing in local races on asphalt (Le Grange in Apple Valley, California) as well as on dirt.

The Arrow uses a 66cc two-stroke Russian-designed, Chinese-built engine called the “Grubee Skyhawk.” The expansion chamber is custom hand-fabricated by Arrow to fit their frame with this engine.

Dave’s initial concept for the bikes was that they would resemble flat-track bikes, since that was his passion and background, so this called for him to manufacture his own frames, gas tanks, and seats. He sourced existing 24-inch wheels and tires, and Shimano drive trains (sprockets, hubs, levers, calipers, etc.) with Avid rotors. The tires are 3-inch-wide dirt-track-style bicycle tires.

The disc brakes on the Arrow are by Shimano. They are hydraulically operated, with Avid brake rotors at each end of the 24-inch wheels.

Dave prefers the 66cc engine called the “Grubee Skyhawk.” Stock, this engine produces 2 ½ horsepower, but with Dave’s modifications, he can reliably get 8 to 10 horsepower, and in this trim the bikes have been clocked at as fast as 50 miles per hour on the street. Total weight of an Arrow Motorized Cycles machine tips the scales at 55 pounds, with 6 ½-inch steel cranks (with standard pedals) and the 24-Sun rims. In this configuration, a buyer can expect to pay in the neighborhood of $1,500; of course, with lighter materials and more custom work, the price will head upward.

Notice the machine work on the intake manifold and head. Arrow puts a lot of custom work into these bikes to take them from 2 ½ horsepower stock up to the 8-to 10-horsepower range when they are finished. Pedals are a stock item with a steel 6 ½-inch crank.

And how does the law regard these motorized cycles/ bicycles? (They do have pedals.) As long as you wear a DOT-approved helmet, adhere to traffic laws, and don’t exceed 30 miles per hour (right…), these bikes are not considered by the DMV to need a license plate or have the need to meet their codes. Think of it this way: You couldn’t keep up with Lance Armstrong on your own bicycle, but on an Arrow, you just might be able to. It’s like performance enhancing without the penalties.
