We're a sucker for a good-looking city bike here at ebiketips and so we were excited when we lifted this out of its box. It's ne new e-Silence Evo from Scott, which features a Brose motor, Contintnetal belt drive and continuously-variable Nuvinci hub.
"The all NEW E-Silence Evo will change the way you look at getting around town", say Scott of this machine. "A revolutionary integrated, silent 508wh Brose Engine will get you where you are going faster and more comfortably than ever before. With integrated Supernova lights and clever carrying systems, you can feel at ease leaving the car at home, silence your city."
Scott lay it on pretty thick on the quietness aspect of this bike. Shimano, Bosch and Yamaha mid motors don't exactly make a racket but you can constantly hear them in the background. The Brose unit is different: because it uses a belt drive to transmit the power from the motor to the cranks it really is a lot less noisy. In the highest assist mode you can just about make it out but below that it's functionally silent, making less noise than the tyres on the road.
That's helped on this bike by the use of a Continental belt drive in place of a chain. Belt drives have become more popular in recent years because they're very low-maintenance and last a long time, exactly what you want from your city bike. You can't split them to fit them, as you would a chain, so the frame needs to be split instead; here the split is at the rack mount.
The battery is very nicely integrated into the down tube of the frame. It's a 509Wh unit and that promises a very decent range for the e-Silence. Scott claim it's a maximum of 150km; you probably won't get near that in real conditions but neither will you be suffering from too much range anxiety. Our experience tells us that a functional range of 50-100km on one charge is more likely, depending on your choice of mode and the terrain you're tackling. Plenty for city use and some longer leisure rides, too.
At the other end of the belt is Nuvinci's Harmony 330 automatic hub. It's a very clever piece of kit indeed, using a planetary arrangement of rotating balls to give a continuously variable drive ratio. It sounds complicated, but it's not really: just watch this...
The Harmony system uses this hub technology and mates it with a cadence sensor and electronic controls to alter the hub ratio automatically and keep your feet turning at the same rate.
The Harmony controls on the e-Silence are very simple: there are three buttons for fast, medium or slow cadence. That's it: the hub and the elecronics do the rest.
At the other end of the bars is the Brose display. It shows speed, assistance level and the battery state, and it also fucntions as a rocker switch to move between modes. The two buttons on the side access the walk-assist mode and turn on the lights; the e-Silence Evo has integrated Supernova lighting at the front and the rear.
The e-Silence Evo comes fully set up for city duties. There's a slimline rack with a bungee strap and a sprung arm for carrying duties, and full Curana mudguards. Schwalbe 50mm city tyres will smooth out the lumps and bumps a bit, and there's a kickstand and belt guard too; belts run much cleaner than chains but you still don't want your good trousers stuck in one.
All that kit (including the heavy hub system) means that this certainly isn't the lightest city e-bike out there, at a nudge over 27kg. And at £3,895 it's at the top end for pricing too. But you're getting a top-spec bike for that, with a very good motor and an advanced transmission, as well as great quality components elsewhere. We'll be introducing the e-Silence Evo to Bath's fine selection of hills and surfaces, and we'll report back with a full review.
