Shimano STEPS 6100 Explained

The STePS eBullitt system includes a 250W, 36-volt electric drive unit, or motor, that will help get you up to speed,?but cuts out at 15.5mph (25km/h). You can go faster than that if you want but any speeds over?15.5mph have to be generated by either pedalling or gravity alone.?The drive unit produces a maximum torque of 50nm or 70nm on the 8000 series and weighs 3.2kg or 2.88kg on the 8000 series, making it one of the lightest on the market.

The current incarnation of the Shimano STePS system has a 416W-capacity lithium-ion battery. The battery is mounted on the frame’s steerertube, balancing the weight.?It’ll take four hours to give the battery a full charge but only two hours to fill it up to 80 percent. Battery life is dependent on mode selection, in Normal Mode the average is 80km, this can vary due to temperature and topography.

Another advantage of STePS over other systems is the combination of electric gear shifting, powered by Shimano’s tried and tested Di2 system. This pairs the Bullitt’s shifting with the main battery for seamless integration through all aspects of the bike. Di2 updates and diagnostics can now be made wirelessly via bluetooth with Shimano’s eTube app. With the shifter cable housed and sealed, the system is incredibly durable and user friendly and multi shifts can be made effortlessly time and time again. One of the toggle buttons on the shifter can also operate the bike’s front light.

Included in the STePS system is a bar-mounted display that shows all the usual info you’d expect with a bike computer, including speed, trip distance, elapsed time and so on, as well as what mode the STePS system is currently in, the estimated range left in the battery and what gear you’ve selected.?The computer is more than just a passive tracking device, however. It analyses the data you generate as you ride the bike and will use this to increase the accuracy of its projections for the estimated range left in the battery.

As well as taking the effort out of pedalling, STePS has intelligent shifting too. With the Nexus 5 hub-gear set-up you can opt for a ‘manual’ version and change gear by pressing buttons, or go choose the ‘automatic’ option and let STePS decide when to change gear for you. The automatic version uses a ‘Symptomatic shifting system’ that senses your cadence and power output, and shifts gears to match them. You can fine-tune the system’s sensitivity so that the shifting occurs at specified cadences. And should you come to a stop while using the system, it’ll automatically shift down so that you’re in an appropriate gear when you set off again.

Incorporating the Shimano STePS system into the Bullitt platform has resulted in the fastest, lightest and smartest cargo bike currently available. Using proven components, frame materials and utilising our accessory line and a decades worth of experience building cargo bikes, we have crafted a bike that is so fun and simple to use.
