The frame geometry doesn't allow a 29" wheel for frame size XS. A 650b (27.5") wheel gives you a better fit and riding experience.

Due to the higher weight of the frame and the force applied by the engine, some parts are subject to wear and may have to be replaced a little earlier than a traditional bike. We recommend you service your E-Bike every 6 months.

A packed E-Bike and the protective bikeguard box measures 159,5 x 39,5 x 88,5 cm.

It’s impossible to give a definitive answer to this question since the range (on any e-bike) depends on several factors including the temperature outside, your weight, your cadence, how you use the power modes, how much you are climbing, etc.
In our own testing, we’ve found the maximum possible range for our SHIMANO STEPS E8000-equipped bikes to be 100 kilometers in “Eco” mode.

A SHIMANO STEPS E8000 is expected to last 1000 charging cycles. However, how you ride and store your E-Bike will impact the battery lifespan.
You might need a new battery if you find your battery no longer reaches it's usual capacity after charging.
