Ducati's top-level TK-01RR electric mountain bike is getting a limited edition, adding carbon fiber parts to the aluminum-framed off-road rider. The Shimano EP8 electric motor and 630-watt battery pack carry over unchanged from the base TK-01RR, allowing for 110 miles of range in Eco mode. The EP8 motor is paired with Shimano's Di2XT electronic gearset, with the motor limited to assist only. This gives the TK-01RR a top speed of 20 MPH and effortless climbing, no matter the grade. The carbon fiber components include Crankbrothers Synthesis wheels, Fizik saddle and Renthal carbon-fiber handlebars, with an upgraded Ohlins fork and TTX rear shock. Ducati will produce only 169 examples of the TK-01RR Limited Edition worldwide.
