Automatic shifting to Shimano groupset brought by firmware update

27th Jan 2016

This new function can be added to Shimano Steps e-Bike groupset.

Shimano have introduced the automatic shifting into one of its e-Bike groupset which take you gear selection out of your hands. The improvement has been applied to e-Bikes using the Shimano Step system with a Nexus Di2 hub which can be introduced by just updating the firmware.

The system works by detecting your cadence, sending a signal to the Di2 hub to shift into an easier gear when your speed has dropped and you are sweating on your pedals, or a harder to gear if you’ve accelerated with your legs spinning like a windmill. The drive unit will then temporarily reduces the chain tension, to give a smooth shifting even when you’re not expecting the system to change gear.

As an added bonus, the system will get you’re riding style over time, so if you’re the type of rider who likes to swirl all day at 60-70rpm, then it will not shift at the same points as it would with Chris Froome, for example, in the saddle, accelerating away at 120rpm. However, if this sounds a little disturbing, the riders has the ability to override the automatic shift system using a small switch on the handlebars.

But this is not the first automatic shifting system we’ve seen, Bioshift also introduced an automatic system that was more aimed at road bikes. This system was due to be available in the summer of 2015, but we’re still yet to see a finished product.
