Jonathan Weinert and I spent some time exploring the latest and greatest updates from Bosch Ebike systems including the CX drive, a new smaller display panel (which still has micro USB charging!) the upgraded 500 watt hour battery pack and a customized Lapierre ebike that won a recent electric bike mountain race called a Boogaloo.
What’s new for Bosch eBike Systems in model year 2017 I asked… and Jonathan really delivered, lots of laughing and fun dry humor here, the guy made these updates fun and that’s great because Bosch is such a big player, takes their systems very seriously and offers such good support as one of the largest ebike drive system makers that it could have been dry and boring. He may have implied that I have multiple cars and that I know “all about speed” which I do not 😉
Jon showed me the bike raced by Victor Sheldon with the custom aftermarket parts including a 10 speed wide range SRAM cassette, ebike specific Fox fork and a funky saddle I wish I would have asked more about… more on the race at http://www.kamikazebikegames.com/races/electric-boogaloo
I learned that the new Bosch Centerdrive software now lets the motor kick in at 20 RPM and is measuring wheel speed, pedal cadence and pedal torque. SRAM EX1 Drivetrain is another update, it’s ebike specific to offer a wider range of pedal speeds. The shifting is super smooth even though there are bigger jumps between the speeds. In addition to the larger battery pack size (which is backwards compatible) there’s a smaller, lighter charger that pushes out 2 Amps vs. the larger standard 4 Amps (just to make it easier to bring along). My favorite part of the whole thing was seeing the inside of the Bosch Centerdrive motor system! They had a clear plastic box with all of the gears, axles and wires showing the inside of the motor at the booth.
The award winning top secret bike was a Lapierre, it’s an Overvolt full suspension model. Got to check one of these a long time ago (an older model) at: https://electricbikereview.com/lapierre/overvolt-fs-900/ with a Fox Ebike optimized mountain biking fork and electronic dropper post and MT7 hydraulic disc brakes.
Also, for dealers, you can take one of the Bosch training and certification courses to get a special dongle that lets you update Bosch electric bike systems and diagnose any issues that customers might have.
