BAD NAUHEIM, Germany - The JD Group, manufacturer of bicycle components and developer of electric technology for electric bicycles, is announcing a new automatic gear shifting system in its TranzX PST powered e-bikes. The cyclist can choose between a fully-automatic or semi-automatic mode to effortlessly change gears.
At Bike Expo in Munich which will start next Thursday, July 21st, the bicycle industry will have the chance to get the first glimps of this new of this technology in detail for introduction in model year 2012.
The Automatic Gear Transmission (AGT) is a computer-controlled system for e-bikes which constantly calculates the optimal gear ratio to smoothly shift to the precise gear necessary to keep the rider at an ideal cadence. Next to that, as the system selects automatically the optimal gear ratio, extensive usage of the battery capacity is avoided.
“AGT is an outstanding innovation that will further boost the e-bike’s acceptance among casual cyclists. By merging this new automatic gearing system with TranzX PST, we are maximizing the potential of e-bikes to their fullest capacity. This is a logical and forward-looking development that will generate new impulses and opportunities for the e-bike market,” says Johnson Cho, CEO of the JD Group in a press release.
Besides a significantly higher level of driving comfort and enhanced riding performance, the AGT technology above all, increases energy efficiency. This is especially important for e-bikes where undershifting or overshifting results in undermining the electric system’s effectiveness. JD’s automatic transmission allows an optimization of the power ratio, generating higher acceleration speeds and moreover achieving greater riding distances.
Without any restrictions, the AGT technology can easily be integrated into TranzX PST powered e-bikes. In particular, the combination of this technology with a coaster brake is an important technical feature and vital benefit for manufacturers catering to casual cyclists.
The Winora Group will be the first to launch e-bike models equipped with JD’s AGT technology during Eurobike 2011. These fully automatic TranzX PST powered e-bikes will be available to dealers for 2012 under the Winora Comfort Series or under the Hercules Touring Series.
