TranzX PST Presents Auto-Shifting for Standard Bikes

 

The JD Group, well known for its TranzX PST drive systems for e-bikes, presented an auto-shifting system for traditional (non-electric) bicycles at this year’s Taipei Cycle. Last year the bike component maker presented its AGT – Automatic Gear Transmission – system for the first time, but then for the use in electric bikes. It was honoured with a Eurobike Gold Award last September.

Bike+ (AGT Bike+) technology is a handlebar mounted, computerized unit that determines when the rider needs to shift and automatically shifts the bicycle into the proper gear. The system features a maintenance free self-charging Lithium battery that attains ranges of up to 500 km. With new AGT Bike+, JD extends its popular and gold award-winning TranzX PST AGT E-Bike technology to conventional bicycles.

Casual cyclists are the primary target group for the new system
The system utilizes a combination of different intuitive sensors – cadence, wheel and tilt – to monitor the road speed of the bike and calculate when it’s time to shift to keep a rider’s cadence steady. Casual cyclists, who want to enjoy a simpler ride without having to worry about shifting into a lower gear in time for a steep hill or higher gear when going downhill, are the primary target group for the new system.

The easy to operate 7-speed internal gear system lets riders choose between a fully automatic and a semi-automatic mode. Riders can furthermore synchronize their preferred cadence by adjusting the gear-shifting rate to one of nine different settings. The system’s computer remembers the rider’s preferred rate and starts there the next time they get on the bicycle. A 7.4V/2.6Ah lithium battery located in the seat tube delivers a range of up to 500 km. A hub dynamo automatically recharges the battery while a light sensor built into the unit checks daylight conditions and activates the bicycle’s headlight as needed.

Available to OEM customers in June
The new AGT Bike+ technology will be made available to OEM customers in June and is due to go into production this fall ensuring that manufacturer’s products reach retailers in time for the 2013 season. At Taipei Cycle JD’s new auto-shifting technology was honoured with the first-ever Taipei Cycle d&i awards. Also the new Gryphon e-MTB model made by JD won an d&i award. Organized and conducted by iF Design GmbH, the awards ceremony was being jointly hosted by the Taiwan External Trade Development Council (TAITRA) and the Taiwan Bicycle Exporters’ Association (TBEA).
