Roehr eSuperSport New And Improved For 2011


Roehr Motorcycles is upping the ante for 2011 and moving from the Hyosung GT250 platform to the beefier GT650 chassis. Roehr is rocking the Hyosung bodywork for the 2011 electric bike instead of rolling his own aerodynamic design as they did in 2010. The new frame is not have a perimeter frame like the previous. The Hyosung 650 frame is designed to use the engine as a stressed member. This probably presented some challenges for Roehr but most likely allowed more room in the end to hang the motor and battery pack off the frame.

Power on the 2011 eSuperSport is up to 67 HP (peak) from last years 48 HP. Weight appears to be up 75 lbs from the 395 lbs I had reported last year.

The choice to stick with the stock bodywork of the Hysoung GT650 should bring the production cost of the bike down. It will also allow customers to utilize the decent supply of aftermarket parts available for the GT650. Windscreens, race wheels, brake upgrades, aftermarket exhaust are all readily available.

The press release below mentions “shunt balancing”. If you are wondering what that is have a listen to episode 11 of the eBike Nerd Cast. Hosts Troy Rank and Greg Crist interview Richard Flechter and Gary Goodrum who built the Zephyr BMS. Skip to 34min 30sec where they explain Shunt circuit cell balancing. The whole episode and all the previous are great too.

Looks like a nice progression for the Roehr ebike line. Hopefully we will see the eSuperSport or eSuperBike on the TTXGP circuit this year.

See the pictures and press release after the break.
