The BionX team was showcasing some updates for their electric bike systems including a semi-clear wheel that shows the inside workings of the D-Series, D-500 direct drive gearless rear mounting hub motor. The Global Training Manager Casey Anderson was on hand to teach me about why their motors don’t overheat as easily as some competing products (the Ultem heat resistant thermoplastic case has more air inside which can dissipate the heat). The Dseries offers increased torque at 50 Nm because of the larger diameter (which creates a mechanical advantage). Also, their spoke design doesn’t connect to the hub, by using longer more traditional straight pull spokes they get flexibility and comfort which is forgiving when riding over bumps or off-road. The battery being displayed was a 317 watt hour but they also offer 423 wh and 555 wh battery with the tear drop downtube. They also have a DC electricity output so you can power lights (there were six Supernova lights built onto the custom Trek Domane frame they were using as a platform). The stack style headlight was custom 3D printed internally by BionX and features two bright beams. Casey explained that the bike can actually hit ~45 km per hour which is available in Europe as a speed pedelec.
Casey also showcased the new DS3 display and RC3 Control systems. Both of these will be available to OEM (original equipment manufacturer) initially in 2016 meaning you cannot get them as a kit right away. I love that the DS3 LCD display panel is removable, can swivel, is backlit and uses a color display designed to be readable in high lighting conditions. The display has a simple easy to read menu but also more advanced settings and is controlled by the RC3 button pad ring. This ring can be used on its own or with some smart phone apps (on some bikes like the Elby in North America and Wheeler in Europe). The ring is super slim but shows everything from your pedal assist level to the battery state of charge and even has a built in variable speed throttle. It’s pretty awesome… The LCD is powered off of the main battery pack so there is only one battery that runs the ebike, the lights (if installed) and the display. The control systems may be Bluetooth compatible for use with some smartphones and other wireless computing devices. Regenerative braking is still included and a single junction is included (usually for the right lever).
Later in the tour Casey Anderson showed me an updated Yuba Mundo with the BionX system installed. They were using a 10 mm axle which has been engineered for strength, heat treated, so it doesn’t have to weigh as much (while most Yuba bikes require a 12 mm axle). All BionX systems are shipped in demo mode, you have to activate them within 100 km and when you do so the owner can register for an additional year warranty (for three years total!) the standard BionX warranty is two years comprehensive. You can check out BionX with www.ridebionx.com for more info or connect with your local ebike retailer. The motor design is setup to reduce cogging (magnetic resistance as you coast) .
