Our story, mission and values

Ampler Bikes was born out of three friends wanting to have practical and stylish bikes that would be truly fun to ride. Being engineers and avid cyclists, this strong drive to create the ultimate city bicycles motivated them to found the company.

Today, we have a team of bike enthusiasts servicing cyclists around the world. Our mission is to make practical yet beautiful electric bicycles that would make personal transport effortless, fast and comfortable. 

All Ampler e-bikes are hand-assembled with great attention to detail in the Ampler factory in our hometown in Tallinn, Estonia.

Difference between Curt, Stout and Stellar


Curt is an athletic and lightweight city e-bike with a sporty geometry. The ride feels firm and highly responsive. Curt is available in two versions: as a single speed with belt drive or as a 10-speed with chain. Compare Ampler Curt Singlespeed VS 10-speed in detail.


Stout is a strong and modern commuter e-bike with the support and comfort you’d expect from a fast city bike. Stout is available in a diamond frame and in colours Pine Green and Graphite Grey. 


Stellar is a modern commuter e-bike with the comfort and flexibility of a city bike. It is fully equipped with everything you need for running errands in the city. Stellar is available in a step-through frame and in colors Racing Red and Space Blue.

Ampler Curt 10-speed VS Singlespeed

Ampler Curt e-bike has two options to choose from: Single-speed with belt drive or 10-speed with chain. 


Ampler Curt Single-speed with belt drive  

The Gates Carbon Drive CDX belt system makes your Curt lightweight and quiet. In addition to the exceptional look, the belt drive is clean, durable, low-maintenance and does not need grease. Carbon fibres give the belt drive a longer lifespan compared to a conventional chain. The single-speed belt drive is the one for you if you live in a mostly flat area where the climbs are either short or not very steep.

The 10-speed configuration gives you all the options to choose from when you next tackle a hill. This setup includes a high-quality Shimano M6000 derailleur with the M6000 10-speed shifter. The 10-gear configuration is for you if you live in a very hilly area where your rides involve long and steep climbs.

Are Ampler e-bikes street legal?

Ampler e-bikes are manufactured according to the standard EN15194 regulations and are street-legal in the European Union. The bikes are labelled with EN15194 marking and the motors have CE marking.

In European Union, according to EN15194 standards, the pedal assist electric bike speed limit is 25 km/h, meaning that the motor supports the e-bike up to max speed of 25 km/h. 

The same goes for Ampler — Ampler e-bikes’ top speed is limited to 25 km/h. However, the actual max speed that you can get with your Ampler depends solely on your muscle strength.
