Motor & Battery Integration THE New Trend at E-Bikes
HANOVER, Germany – Brose, TranzX, Conti are just a few examples of e-bike system suppliers that offer integration solutions. At the earlier this month held Eurobike show they presented what mid-motor and battery integration brings. And that’s for all better looking (electric) bikes.
Soon an end will arrive to those outdated looking frames on which mid-motors are simply bolted on. These crude looking frames will be replaced by ones that look slim and sleek despite the fact they house almost all electronics needed for a well-functioning e-bike or speed pedelec.
Conti is one of the e-bike drive system suppliers that presented a fully-integrated downtube battery for its 36 Volt Conti eBike system. The integration solution Conti offers consists of a specially developed downtube frame element accommodating a battery, battery management system, and motor adapter. OEMs can easily integrate this into their frames. It will enter production at Continental in 2017.
At TranzX the first fully integrated frame-drive concept is named Integra. It integrates the mid-motor and a specially designed battery into the frame. This grants TranzX Integra its greatest advantage. TranzX claims that, “The deep-seated mid-motor and the arrangement of the batteries ensure an excellent weight distribution, safe handling and increased riding comfort and design.
Highlight of Integra is the TranzX Flexpack–a flexible down-tube battery, which makes insertion and removal very easy. Using a small loading flap on the down tube, the battery can be removed for charging. The battery pack is available in two different versions: As FleXpack33 (40V, 408 Wh, 2.4 kg) or as FleXpack32 (40V, 272 Wh, 1.6 kg).
The TranzX Integra line is suited for use with the compact TranzX F15 front hub motor as well as the M16 and M25 mid-motors.
