About this project
Derringer is a well known builder of custom, board track inspired motorized bicycles. Every Derringer is hand-built to customer specification in Los Angeles, California. Customers love the look and customizability of the gas powered models, but many expressed interest in an electric model with ease of use, low maintenance, and great reliability.
The wait is over. Now you can own a classically styled, truly unique electric motorized bicycle, ready for daily commuting, weekend cruising, and everything in between, no oil changes required.
Board Track Inspired
Board Track racing, one of the most popular spectator sports of the early 20th century, got its start in Los Angeles with the construction of the Los Angeles Motordrome in 1910. Board track racing motorcycles were essentially beefed up bicycles with powerful engines that allowed riders to reach mind-boggling speeds on circular wooden tracks. It was truly one of the most exciting and dangerous spectator sports of all time. Los Angeles was home to three tracks over the years, with facilities built in Beverly Hills and Culver City, in addition to the original in Playa del Rey. The new Derringer Electric captures the style and feel of these historic racing machines, and combines it with modern technology to create a one-of-a-kind mode of transport, as beautiful as it is fun to ride.
Made In USA
The foundation of the Derringer Electric is the custom, hand-built frame. Adapted and refined from the classic gas-powered model, the frame was redesigned and CAD modeled in Los Angeles. It features chromoly construction, custom pistol shaped dropouts, and elegant flowing curves, giving you the strength you need, while standing apart from the rest. Each frame is TIG welded by master framebuilders in Portland, Oregon. Every Derringer Electric bike is individually assembled by hand in Los Angeles, California.
Head Turning Style
Have you been disappointed with the dull, utilitarian electric bikes on the market today? While styling appears to be an afterthought on many imported E-bikes, simple, elegant, sporting looks were a goal for the Derringer Electric design. The battery resides in an enclosure inspired by the fuel tanks from vintage board track racing motorcycles. It mounts in close proximity to the motor controller, minimizing unsightly wiring. The motor controller resides in a vented enclosure styled after the rear mounted oil tanks and tool boxes on early vintage motorcycles. For Heritage and Signature Series bikes, the battery and controller housings will be fabricated from a combination of glass fiber composite and aluminum in San Diego, CA, and painted to match the powder-coated frame. Bespoke Series bikes feature enclosures with full aluminum construction, made in Santa Rosa, CA, and available with a brushed or painted finish. The Derringer Electric also incorporates a classically styled chromoly springer fork with an IS disc brake mount and a 1 1/8” threadless steerer for a wide range of component options.
At the heart of every Derringer Electric is a powerful lithium-ion (Li-NMC) battery. This safe, reliable chemistry allows for high current draw, has great energy density, and still provides a long lifetime of 1000 recharge cycles. Bikes are available with 37, 52, and 63-volt batteries, each with a 12.5 Ah capacity. Heritage and Signature Series bikes include a 4 Amp charger that can recharge a fully drained battery in three hours. Bespoke buyers get an upgraded 6 Amp charger that drops charging time to two hours.
Propulsion comes from a brushless hub motor built into the rear wheel. All motors are wound for high torque, providing stunning off the line acceleration and aggressive hill climbing ability. All models come standard with direct drive (gearless) motors, which are incredibly reliable, quiet, smooth, and able to handle high current loads. Signature Series 52V bikes are also available with a geared hub motor that employs a planetary gearset to reduce size and weight, for customers that prefer a compact unit in lieu of motor power handling ability. Power is applied with a twist grip throttle, similar to the ones found on motorcycles and scooters.
All bikes ship in USA street legal mode: 750 watts and 20 mph maximum speed. Signature and Bespoke Series bikes feature a Cycle Analyst E-bike computer, allowing owners to tune the bike to their individual power needs all the way up to 2000 and 2800 watts respectively.
High Quality Components
A powerful bike needs powerful brakes. Every Derringer Electric comes standard with hydraulic disc brakes from German manufacturer Magura. These high quality brakes provide fantastic modulation, modern design, and formidable stopping ability. The Magura electric throttle, offers intuitive control similar to that of a motorcycle, and far superior to the cheap plastic Hall effect throttles found on most E-bikes. The Cycle Analyst E-bike computer, made in Vancouver, BC, provides a wealth of information on its large backlit LCD including speed, distance, battery info, power, net energy, and more. This sophisticated computer also allows for rider control of the system power output and speed limit. Every Derringer also includes a Brooks leather saddle, handmade in England, cartridge bearing threadless headsets, and high performance Schwalbe tires.
Make It Yours
Derringer is known for customizability and the Derringer Electric is no exception. Heritage Series buyers can choose either a Brooks Flyer or B67 saddle in black, brown or honey brown. Customers may also select board track style drop bars or cruiser style risers. In addition to saddle and handlebar options, Signature Series buyers can choose from six colors and may select a direct drive or geared hub motor.
Bespoke buyers can select any colors from our chart for the frame, rims, and spokes, as well as detail colors for the aluminum tank. Derringer also offers a variety of tire options suited to each owner's riding needs. Every Derringer is powder coated with Tiger Drylac outdoor rated powder coatings for beauty and utility. Battery and controller housings are painted to match on Heritage and Signature Series, or can be brushed aluminum on the Bespoke Series.
- Range estimates are based on a 170 lb rider traveling on flat ground at a constant speed of 20 mph, without pedaling. Many factors will affect actual range including: rider weight, hills, and speed.
- Power figures are maximum system output at the nominal battery voltage. Many things will affect actual watts including: rider weight, hills, battery state of charge, and speed.
- All bikes will be shipped limited to 20 mph and 750 watts as per US regulations. The rider assumes responsibility for complying with all local laws if the bike is ridden on public roads.
Risks and challenges
Frame Production - We need to have tooling made for the production of our frames. In addition, slight modifications to the design may be necessary to ensure that the frame is production ready. We are enlisting the help of a master framebuilder and a CAD designer to ensure we get the best quality product the first time around, and will work tirelessly to minimize any delays that may arise.
Component Supply - We rely on our suppliers for a constant supply of components that can keep up with production. If some key parts go out of stock, this has the potential to delay some aspects of production. We are working with all domestic suppliers to ensure that there is always plenty of information on stock, and so that potential problems can be dealt with in a timely manner by experienced individuals.Learn about accountability on Kickstarter
