In what is turning out to be a huge week for electric motorcycles, Roehr Motorcycles introduced today a line of electric superbikes (motorcycles) including a “race ready” model. The eSuperBike range includes three models, the entry level eSuperSport has a single 48 HP AC motor and an MRSP of $16,995, the eSuperBike has dual AC motors for 96 HP total and an MRSP of $27,559, and the race ready eSuperBike RR also has dual AC motors for 96 HP total and an MRSP of $34,495.
eSuperSport: Their entry level model, offers a 100 miles/hr top speed, dual disc brakes, 41mm USD forks, a single rear suspension, a single 48 HP AC Induction motor, direct drive (no transmission), a 96 volt 60 amp-hour 5.8 kilowatt-hour LiFePO4 battery pack (aka lithium-iron-phosphate, LiFePO4 is one of the lithium battery chemistries).
eSuperBike: Their high end model, offers a 135 miles/hr top speed, dual Brembo disc brakes, 41mm USD forks, Ohlins rear suspension, dual AC Induction motors for 96 HP total, direct drive (no transmission), a 96 volt 80 amp-hour 7.7 kilowatt-hour LiFePO4 battery pack.
eSuperBike: The race ready version of their high end model, offers a 135 miles/hr top speed, dual Brembo disc brakes, 43mm Ohlins forks, Ohlins rear suspension, lightweight aluminum racing wheels, dual AC Induction motors for 96 HP total, direct drive (no transmission), a 96 volt 80 amp-hour 7.7 kilowatt-hour LiFePO4 battery pack. This comes track-ready with all required safety and racing equipment for TTXGP or e-Power racing.
Roehr has not published information on range or charging time. All bikes come with an on-board chargers (either 15 amp or 6 amp rate) so by doing the numbers (6 amps a is 576 watt charge rate, 15 amps is a 1440 watt charge rate) indicates a 6-8 hour charging time from full discharge for the eSuperBike while the eSuperSport would have a 3 hour charging time due to the higher charge rate. Having on on-board charger on a race bike appears odd due to the desire to minimize weight, presumably that charger is easily removable.
The controller is specified at 600 amps continuous (57.6 kilowatts) and 900 amps max (86.4 kilowatts) for the eSuperSport and 800 amps continuous (76.8 kilowatts) and 1200 amps max (115.2 kilowatts) for the eSuperBike.
Roehr first announced the eRoehr series in January. Reports from that time state the eRoehr bikes would be hitting showrooms in April and be at the TTXGP race in May. Neither of those happened, until now with this announcement.
Reports from January also state the motor and controller system comes from “High Performance Golf Carts,” a company that sells a kit containing an AC motor and controller. That kit is obviously targeted at souped up golf carts but the it is a popular kit for electric motorcycle builders. Many of the TTXGP teams are using this same kit on their race bikes. No mention made by Roehr of a cooling system. One issue plaguing TTXGP racers is cooling the motor and controller. Close inspection of the pictures reveals possible air intakes on the fairing.
These motorcycles are available through Hollywood Electrics in Los Angeles, through Ethical Approach in Los Gatos, and factory direct through Roehr.
