The Perfect urban E-Bike. Lightning quick on open roads as well as agile and nimble through traffic.

 The Delta S is the perfect everyday commuter bike: fast, light, and reliable with a 60km range. Proudly built in the Netherlands.

Features

Lightweight and Agile - The 16kg Delta S is built for speed! The powerful rear-wheel motor lets you fly through the street effortlessly. The sportive geometry allows for an exciting and dynamic riding experience. Perfect for navigating busy city streets.

No Chain - Don't let oily, rusty chains stop you. The Delta comes standard with the unstoppable Gates Carbon Belt Drive system. The Gates belt drive system is light, clean, and maintenance-free.

Intuitive Assistance - With a single gear, you never have to think to switch. The small powerful rear-wheel motor perfectly matches the level of assistance to the speed you need in every situation.

The assistance feels natural and intuitive thanks to the Thun X-cell 3.0 torque sensor in the bottom bracket.

60km of Range - With a full battery, the Delta S has a range of 60 kilometres. More than enough for your daily commute while keeping the weight of the bike low. A full charge takes just two hours. But even with an empty battery cycling on the lightweight Delta S feels effortless.

Ride Safely - See and be seen. The Delta S comes with a high-quality and powerful made-in-Germany Supernova head and tail light. The semi-integrated lights make sure you can ride your Delta safely at night.

Maximum Control - The Magura hydraulic disc brakes give you maximum control on the road in all weather conditions.

Ideal For Commuting - Cover the distance between your home and work effortlessly and relaxed. The Pletscher fender with integrated pannier mounts, Brooks Cambium C15 saddle, and Ergon GA3 grips make sure your ride is comfortable and enjoyable.

Smart Connectivity - With the connected app you can find the quickest route, look up previous rides, check the battery level, and select a power mode. Via over-the-air updates, they keep the firmware inside your bike always up to date.

As an add-on, you can protect your Delta S with active GPS tracking. Through the App, you can see where your bike is at any given time. Digitally lock your bike when parked in the App and get notified when your bike is moved.

Made in the Netherlands - The distinctive design of the Delta S is the result of a unique automated frame production process, developed by Mokumono. The innovative production process allows us to produce in the Netherlands.

They show that bicycle frame production in Europe is still possible and that is something they are very proud of.

How it works

Never ridden a single-speed electric bike before, and need a quick explainer on how it works?

Well, first things first: it’s not a motorbike. Don’t expect to coast along, not pedalling at all — the motor requires some effort from the rider to engage.

Basically, e-bike drive systems are designed to provide assistance relative to current conditions; that is, they react to resistance (whether it’s from rider weight, effort, wind direction, weather conditions, etc.) and output assistance (power) accordingly.

Of course, the main form of resistance on a bicycle is gravity, i.e. hills. Unlike on a non-electric single speed bike — when a rider will have to put out massive amounts of power to maintain speed and cadence as the road increases in gradient — on an e-bike, the internal motor will provide powerful forward thrust, allowing rider effort to remain largely the same.

While your speed might drop — don’t expect to be dancing up the hills à la Contador, with or without a motor! — the assistance provided will mean you can maintain a steady power output and arrive at your destination relatively sweat-free.

Just make sure to keep that battery charged.
