Gates Carbon Drive Unveils Concept Pedal-Assist eBike Using NuVinci® N360™

(Gates), a division of Gates Corporation, and Inc. (Fallbrook) today announced the presentation of a benchmark concept eBike, featuring Gates’ CenterTrack™ belt drive system, Fallbrook’s N360 drivetrain and Bosch’s eBike system.

Gates’ technical mastermind Karlheinz Nicolai, known as a non-conventional designer, researcher and developer of benchmark setting products like the Smart Pedelec and the Grace e-motorbike, has spearheaded the combination of these three individual and synergetic systems to produce this advanced Pedelec.

Nicolai/Gates/ Concept eBike – Feature Highlights

  • To achieve full integration of the battery, the down tube is divided into three parts with the battery inserted from below. Composite or plastic side panels can cover and achieve a cohesive design requirement.
  • With this special battery integration, the top tube can be lowered, achieving a Mixte frame with a sports look Lady Geometry.  For all weather and everyday commuting the eBike can be equipped with any protective and practical accessories like fenders, rack, lighting, etc. A MTB application requires additional dirt and debris protection covers for the battery.
  • The electric motor is fully integrated into the frame (rotated 45 degrees up).
  • The location of the motor unit enables a short rear triangle and compact chain stay section and offers plenty of ground clearance.
  • All cables and wiring are fully integrated into the frame.

Gates’ Drivetrain Revolution: Lighter, Cleaner, Stronger
Gates’ new CenterTrack drive leads to a 20 percent more tensile strength, a slimmer profile and the most advanced dirt- and debris-shedding compared to conventional bicycle chains. “The CenterTrack is a quantum leap forward for belt-drive technologies. It offers all the clean, quiet and strong advantages of our existing drive trains but with an even higher level of performance,” said Todd Sellden, Director of Systems.

Wayne Lumpkin, former head of Avid, inventor and one of the most innovative thinkers in the , adds: “CenterTrack makes cycling easier and more enjoyable. Being the most robust bicycle belt-drive ever, lower maintenance is guaranteed.” The slimmest ever produced pulley and the slender profile makes it simple to integrate with drive trains such as the N360.

Perfect Pedelec-Player: N360 Drivetrain
Perfect for use with pedal-assist bicycles, the N360 features an infinite number of ratios available within its nominal 360% ratio range, giving riders a shifting experience unlike any other. The N360 CVP enables cyclists to easily maintain an optimum cadence regardless of terrain, and makes shifting as easy as adjusting the volume on a radio. The system includes a durable, permanently sealed hub that is maintenance free and requires no adjustments or regular servicing.

Chris Vasiliotis, Product Manager, said, “With the N360, shifting is easy even under high torque pedal-assist conditions, and there are no ratio gaps, missed shifts, shift shock or noise.  Riders feel comfortable shifting at any time – without the penalties of indexed geared systems. The simple, seamless eBike experience can result in extended battery life, reduced motor wear and, ultimately, increased range.”

Power Up With Bosch eBike System
The Bosch eBike system has captured the spotlight since its introduction at last year’s .  Thanks to the versatile motor positioning, this system offers the perfect solution for any type of bicycle – including sports or casual bikes. The software allows for optimal customization, plus the drive unit can be operated in one of four different modes – including eco, tour, sport, and speed – each suited to the rider’s preference. “This enables s to tailor their products according to their selected target audience,” said Rainer Jeske, Senior Vice President Bosch eBike Systems.

Bosch also invented its own battery system which draws on the company’s experience of producing exceptional lithium-ion batteries and chargers for its power tools.
