Epo-Bike First Confirmed FIM ePower Entry


Christian Amendt, an engineering student out of Germany is the first confirmed entrant of the 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 115 Kg (253.5 lb) electric race bike weighs 187 lbs less than the triple motor MotoCzysz e1pc. The theory is 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 (predecessor of Agni 95) 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.

Like most of the “exclusive” TTXGP entries, it does not seem Amendt has anything against the competing series. The FIM ePower series is merely more convenient given his location and time constraints. This is a step in the right direction for ePower who has seen TTXGP gain a hand full of entrants over the last few weeks. FIM will run ePower races on WSBK and MotoGP race weekends which should have a strong draw for race teams looking for visibility in the up and coming electric race scene.

    “The Epo-Bike uses an undisclosed DC motor, LiFePO4 batteries from an undisclosed manufacturer ”

    Looks like one Agni motor (might be a Lemco motor too), and Headway 38120S cells.

    I like :)

    Yeah, your right. Ivar had stated it is a Lemco D135 motor.

    This is the direction I could see Brammo going in for a race machine. Being a worshipper of all things Colin Chapman, I think the Epo-Bike is a great approach. Very cool.

    Nice work Christian. The cells can be clearly seen to in the photos to be Headway 38120S cylindrical lithium iron phosphate cells. Competition improves the breed!

    I believe those cells are from Headway. I have a pack made from Headway cells and the color of both cell and plastic frame are exactly the same as the pack I have.
