A2B launches Entz e-bike with frame-integrated motor and gearless shiftingView gallery - 10 images
Electric bike specialist A2B introduced its latest creation at last month's Eurobike show. Named after the American inventor of the electromagnetic transmission, Justus B. Entz, the Entz e-bike benefits from a new, neatly integrated Continental e-drive that saves weight while promising a sharp electric-assisted ride.
The aluminum-framed Entz is among the very first e-bikes to feature Continental's CONTI eBike drive system, which also debuted at Eurobike 2014. The CONTI packages a motor, backlit display, remote control and battery into one system, and A2B reckons it's one of the lightest, smallest, most powerful e-drive packages out there.
The CONTI drive's central motor is integrated directly into the Entz's frame. That 7.5-lb (3.4-kg) motor packs 250 watts of pedelec power and can engage the rear wheel through the buyer's choice of manual Shimano Alfline eight-speed hub or manual/automatic NuVinci Harmony gearless hub. The motor powers the bike to speeds of up to 15.5 mph (25 km/h).
The Entz uses a rear carrier-mounted lithium-ion battery that offers up to 62 miles (100 km) worth of pedelec range and charges in 2.5 to 3 hours. The rider controls the system by way of Continental's Eurobike/Red Dot Award-winning remote control, which is integrated seamlessly in the handlebar grip. The backlit display shows battery life, speed, distance and other metrics.
Other Entz components include a Suntour suspension fork with 2.5 in (63 mm) of travel and 24 x 2.35-in Kenda Krusader tires. A2B lists the curb weight at 61.5 lb (27.9 kg).
The new Entz is a redesign of an Entz model that was supposed to launch last year. A2B told us that it had technical issues with the 2013 Entz that meant it never started production on it. To create the new model, it tweaked the frame, replaced the original e-drive with the new CONTI system and changed out other components.
The German-built Entz will launch in Europe in January and the US in March of 2015. The Deluxe model will include the NuVinci gearless hub and a larger 14.5 Ah battery that offers the 62-mile (100-km) range versus the standard model's 11.25 Ah battery and 46.5-mile (75-km) range. Final pricing has not been set, but A2B expects to price the standard model at US$3,999 and the Deluxe at $4,999. The bike will come in both 16- and 20-in frame sizes.
