Our good friend Christian Amendt has a project that he’s sharing with us this week. Taking a break from his EPO-Bike electric racing motorcycle that he’s campaigned in the FIM e-Power series, the German student has built something a bit smaller, but equally fun. Complete with a 7kW brushless DC motor and .9kWh of battery on-board, we’re dubbing this electric pocket bike the “EPO-Pocket Bike” until Christian comes up with a more suitable name for the pint-sized terror.

The EPO-Pocket Bike is good for about 15-20 minutes of ride time with its current configuration, and according to Amendt is a lot more fun, with less vibration, that its ICE counterparts. Amendt’s creation is geared to 40 mph, but power wheelies are possible all the way to 25 mph with a crack of full-throttle.

Asphalt & Rubber got this email late last night from one of the competitors at the e-Power race at Laguna Seca this past weekend. It shows a rare glimpse into the electric racing scene, that even our own coverage can’t compare to in storytelling ability. The letter talks about sportsmanship: the sportsmanship that riders and teams share with each other, but also more importantly the sportsmanship that makes others take notice, and strive to be better. Read the letter after the jump.

Christian Amendt, an engineering student out of Germany is the first confirmed entrant of the FIM ePower Electric Motorcycle Race series. Using what might be called a quantified version of Lotus’s “performance through low weight” philosophy, Christian converted a Honda RS125R to electric using a “half the weight, half the power” design.

The 115kg (253.5lbs) electric race bike weighs 187 lbs less than the triple motor MotoCzysz e1pc. The theory is that the light weight will allow the 96 Volt, single motor, 3 kWh Epo-bike to out perform a 2 or 3 motor bike that weighs over 400 lbs with the batteries needed to power them. The Epo-Bike uses a Lemco D135 DC motor, LiFePO4 batteries from an undisclosed manufacturer and an Alltrax AX7425 controller to achieve 74Nm of torque and reach a top speed of about 111 mph.
