Deliveries to begin in the summer.

Roehr Motorcycles has released more information about its line of electric sportbikes including two street models and a higher-spec racing version.

The Illinois-based manufacturer announced its entry in the electric motorcycle segment in January with two eRoehr models, the eSuperbike and the entry-level eSupersport. They will be joined by the Roehr’s new flagship electric sportbike, the eSuperbike RR which was designed to compete in the TTXGP and the FIM’s ePower racing series.

According to Roehr Motorcycle founder Walter Roehrich, development of the electric models had fallen behind, and the eSuperbike RR will not be ready for the start of the TTXGP series. Roehrich told Motorcycle.com there is a chance the eSuperbike RR would ener the TTXGP late in the season but 2011 would be more likely.

“The mechanical portion of the bikes are completed, we are in the testing and development process right now, both on the dyno and the street. We were planning to be a little further along by now, and were hoping to enter the TTXGP series, however a few delays, mainly with bodywork tooling have set us behind schedule a bit,” Roehrich wrote on the electric motorcycle forum ElMoto.net. “As much as we would have loved to compete at Infineon next week, our main priority is to finish our development, and deliver a refined quality product with confidence. Like the eSuperbike production model, the RR version will use twin AC induction motors with a claimed output of 96 hp and 210 ft-lb. of torque. The motor will run on a 96V lithium-iron-phosphate battery with a capacity of 9.6 kWh.”
