ROEHR announces new 2011 eSuperSport electric motorcycle
ROEHR's new 2011 eSuperSport electric motorcycle
Illinois-based ROEHR Motorcycles has announced a 2011 update to last year's eSuperSport model. The new entry-level performance superbike's design is now based on the award-winning Hyosung GT650R, it's been given a power boost, has a top speed of over 100 mph and its onboard battery is said to be good for 75 miles before needing some charging attention.
ROEHR has revealed that its new 2011 eSuperSport has been built around a twin oval tube steel beam frame and its single speed direct drive AC induction motor offers 67hp (50Kw) peak power and 80 pounds per foot (11.06kg/m) torque, with a top speed in excess of 100 mph (160+ kph). The Lithium Iron Phosphate LiFePO4 high discharge cylindrical cell battery solution has a 7.7 Kwh capacity that should be good for 75 miles (120 km) before needing to be topped up using its 1500 watt onboard charger, which offers a recharge time of seven hours. An eROEHR Battery Management system controls the charging functions, low voltage intervention and shunt cell balancing.
The eSuperSport is said to deliver the kind of handling and braking performance demanded by today's sporting motorcyclists - benefiting from inverted suspension at the front with adjustable rebound and compression dampening and single shock rear suspension with adjustable rising rate linkage. There's dual disc brakes at the front with four piston calipers, and the six spoke aluminum wheels front and rear respectively sport 120/60ZR17 and 160/60ZR17 Bridgestone tires.
The 470 pound (213 kg) REOHR eSuperSport is available now for a suggested retail of US$17,995.

You should be able to install sounds like a ringtone. I personally would have mine sound like a starship from Star Trek.
Is that charging time @ 110v or 220v?
I'm all for electric motorcycles/vehicles, but heres the downside:
Traffic cant HEAR YOU. If motorcycle riders are at constant risk form being run over because people cant see them imagine what could happen to someone on a bike no one could hear because i'ts silent and electric PLUS they still may not be seen. Its kind of scary but still cool.
Size does matter like the Sora electric motorcycle concept ( http://www.gizmag.com/lito-sora-electric-motorcycle/18455/ ). It big and powerful so someone may see you......speakers are the answer. I personally think simulating the rumble of a bike engine....thats the answer to being seen and heard. It's safer.
Great to see an e-bike that still looks like a bike! Good job ROEHR!
Hey Jens, as a biker, sound isn\'t the only or best way to be \"visible\" on the road. Many drivers have their sound systems turned up loud anyway, so relying on the sound/noise of your bike is a false hope. The deep sound emitted by a large twin isn\'t easy to locate, so while it might be audible, a driver will have difficulty identifying where it comes from. Many existing ICE bikes don\'t \"rumble\", particularly 4-cyl 600cc bikes built for lightness and speed.
The best way to be seen is through your riding behaviour. It doesn\'t matter much what you ride or how it sounds, it\'s how you ride that keeps you alive.
I would trade a top speed of 70 to 80 mph with a range of 250 miles, I would buy that, this, no
Without great difficulty an owner of a machine such as this could add on a \"range extender\".
To keep up the sportsbike style; I would choose to make THAT in the form of a single-wheel trailer- like a UniGo, N-Line, or the Mono-Trail Tour MAX (although I\'m not a fan of the axle-coupling types).
Simply explained; when one needs a longer range than straight E-power provides, the easy option is a range-extending generator trailer that gives one all the benefits of a hybrid. When the owner is only riding short range, the trailer is uncoupled and stood-up against the garage wall. (A further benefit is having some luggage capacity on-top of that range-extender.)
Good to see some enterprises are moving on from the e-scooter or the e-supermoto to a \"real\" looking bike (tho I\'m not too big a fan of the back-wrenching tuck position this type requires.) I hope this is a sign that a broader range of options is becoming available. (Anyone over at kikker5150 listening? An e-bobber or e-cafe would be sweet, eh?)
I also love that they\'re using LiFePO4 batteries. This chem formulation is much safer than many other lithium options (no \"boom\" if they get too hot.) One further improvement would be to change those nice twin front brake discs for regen units. Other than that (and that sky-hi price) this baby\'s lookin great! Kudos, ROEHR!

et al who would prefer a commuter bike.

100 MPH great! 75 Mi range! Cool! 50 kw peak output, hmm. 7.7KWh storage. Hmm.
So, 100 MPH for 11 minutes? 9 miles later and it\'s dead?
My point is the article doesn\'t disclose the conditions the 75 mile range is based on.
All downhill? More fact, less poof please.
Increase the range with a lose of top speed is good. Who ever rides at the speed on the road anyway?
Even if you have a \"sleath\" orange or fluoro green bike you are still invisible. I had way too many close calls from \"not being seen\", to the point of giving up riding.
A way cool concept. Just look at the Isle of Man lap record for electric bikes to see how far technology has come
