Bosch has lengthy been a pacesetter within the premium electrical bicycle drivetrain market and now appears to be like to additional construct on its sturdy basis with the launch of a number of new merchandise. Electrical mountain bikes (eMTBs), that are a staple of Bosch’s e-bike prowess, are more likely to profit most from the brand new motor and bigger battery choices.
Chief among the many unveilings is what Bosch is looking “the following evolutionary step of the Efficiency Line CX”, which is likely one of the model’s flagship motor programs for electrical bikes. The drive unit line has been in the marketplace for almost a decade, present process a number of updates and upgrades over that point interval.
The most recent model of the motor system is claimed to make use of “delicate sensor know-how” to supply “dynamics on a complete new stage.”
The corporate claims that the drive system’s re-engineered sensor know-how exactly measures pedal enter greater than 1,000 instances per second utilizing a set of cadence, torque, and intertial sensors. The drive unit also can sense incline angles in addition to vibrations, which it makes use of to extra exactly ship energy when wanted – a function more likely to be useful on mountain bike trails.
“With 85 Newton meters of torque, a most energy of 600 watts, and as much as 340 p.c help, the brand new Efficiency Line CX (BDU384Y) delivers the perfect stability of energy, dynamics, effectivity, and vary,” says Claus Fleischer, CEO of Bosch eBike Techniques. “Whether or not for delicate begins on steep trails or highly effective, completely managed exits from curves: With its exact, delicate response conduct, our new drive unit permits athletic eBike riders to expertise distinctive using dynamics for the proper eMTB expertise.”
Bosch can be touting a brand new quieter gearbox within the drive system, which the corporate says has been optimized to attain a superb stability between energy supply, effectivity, and noise ranges.
The exterior drivetrain, consisting of the chainring, chain, and cassette, can decouple when using downhill, which helps to scale back noise additional.
Serving to preserve monitor of simply how briskly these rides are going, together with a complete host of different information, is Bosch’s new Purion 400 show.
The show makes use of a 1.6″ display screen that’s particularly tailored for electrical mountain bikes. It’s designed to be tucked in behind the handlebars of electrical mountain bikes the place it may be higher shielded from harm throughout crashes.
Additionally excellent for mountain biking is Bosch’s new PowerTube 800, which is the corporate’s largest electrical bicycle battery produced thus far. With the flexibility to run two batteries without delay, dual-battery e-bikes with a pair of PowerTube 800s will have the ability to provide 1,600 Wh of capability.
Whereas such capacities are beginning to turn into extra widespread in lower-end e-bikes that are inclined to throw extra motor and battery on the drawback, premium e-bikes like these carrying Bosch motors have lengthy taken a ‘much less is extra’ strategy with regards to battery capability. The shortage of a hand throttle on Bosch e-bikes additionally implies that they typically run longer on the identical dimension battery, permitting using smaller packs than throttle-enabled electrical bikes. However now with 800Wh of capability, Bosch’s largest battery pack is on par with lots of the different largest packs in the marketplace.
The corporate additionally introduced a brand new PowerTube 600, for individuals who don’t want fairly the large battery capability discovered within the PowerTube 800. And for individuals who solely often want the additional vary, the PowerMore 250 water bottle-sized battery might be added to e-bikes as an auxiliary pack.
