The day-to-day has just shifted a gear. Grab a Diem and seize the day!

Quality. A Step Above

Diem is built on a deep understanding of performance, design and the belief that riding should be enjoyable. That means an elegant design, removing anything superfluous, and pursuing simple solutions. Considering the design as a whole, right from the start, including the highest quality components and accessories, means Diem is a collection of details which work together to give a riding experience way beyond other city bikes.

Hydroforming and butting our aluminium tubing gives us more control over the material, enhancing the design, reducing weight, and optimizing the frame rigidity. Balancing rigidity and weight is vital to improve handling and add fun. The final step is our High Polish finish, where the welds are polished to make them invisible giving Diem that smooth look. Diem's intelligent lighting system is designed to keep you visible day or night. The rear light intensifies as you brake, helping alert the traffic behind you. The additional front beam automatically switches on in the dark to make sure you are seen and let you see the way ahead.

Performance. Enjoy Every Ride
Diamond Glide is a patented design that allows the frame to flex vertically, absorbing bumps and giving a smooth ride on rougher streets. The combination of our carbon fork and wider tyres helps absorb the bumps of rough streets.

Diem's new Urban geometry keeps the weight low and centered meaning fast reflexes and inherent stability, vital for slotting through the urban jungle. Designing a frame to do all this, while also making it easy to keep track of what is going on around you is a balance and takes careful consideration.

Safety. Safety Built Into Every Journey
Every Diem has a built-in, high-tech lighting system which automatically switch on to keep you safe and light the way ahead. The front beam switches on automatically at night to increase your visibility even if the streets are dark. The wrap-around lights make sure you are always visible, day or night, even from the side. The reactive rear lights brighten to announce braking. 

The Supernova Starstream headlight is integrated into the handlebar or the front of the optional rack. As well as being protected from damage or theft, this removes obstructions from the light beam, making you more visible. If you choose the optional, Supernova Starstream dual beam light, you can easily switch between the low beam and the bright high beam.Our headlight, rear lights and the integrated wrap-around lights are StVZO compliant.

Our integrated Spin Block system prevents the handlebars from rotating too far, making it much easier to load and unload your bike. No matter which model of Diem you choose you can count on robust, high quality tyres, with internal reinforcing to protect against punctures and reflective strips on the sidewalls to make sure you are seen.

Hidden on Diem’s motor cover is a space to mount an airtag if you want. You can mount an AirTag or any compatible tracker. The advantage of this system is that it allows users to find the best option for specifics of their city. Diem comes with our Quality Guarantee which we back up with a lifetime warranty.

As one of the world's leading ebike motor manufacturers, Shimano's EP motors offer simple, reliable service day after day, as well as an extensive network of service centers if you ever need them. The subtle remote is easy to control without moving your hands from the bars. The integrated LED lights tell you which assistance mode you are in. If you want more information then it is easy to connect your mobile, add it to the included mount, and access detailed system information.

The SBS system securely fixes the battery inside the bike frame. As well as making the battery impossible to steal, SBS allows us to design better looking, slimmer frames which are lighter and stiffer, resulting in faster reactions and added control when you are zipping
around the city.

Most people will never need the extra range that the modular battery offers, however it can be useful to take up to your office to charge. The 252Wh range extender (available separately) slots easily into the bottle cage and provides instant extra charge. 

Everything You Need. And Nothing More.
Diem offers 20 kg and 30 kg rear carriers compatible with Ortlieb and MIK systems along with an optional 10 kg front rack and basket. Our optional adaptor makes Diem 10 and Diem 20 compatible with Thule, Burley, Croozer and Hamax trailers. Diem 30 works with conventional thru axle adapters.

The low-slung frame makes it easy to mount and dismount, adding security, even if you have to come to an unexpected stop. Diem's frame design keeps the upper tube, which is vital for rigidity and adds control and precision to Diem's impressive handling.

The integrated kickstand pivots from the center of the bike and also integrates neatly when not in use. It is complicated to design, however the benefits are clear, with increased stability and security.

Integrating cables and switches in the handlebar means everything you need is right at your fingertips so you don't have to move your hands from the controls. Less cables means less distractions and gives more space for accessories such as your phone or the front rack.

Our one piece stem and handlebar is designed to make mounting your mobile phone secure and easy with the integrated SP Connect system. The top tube power outlet offers a USB-C connection for charging your mobile phone on route.
