About Ampler e-bikes

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.

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.

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.

All our e-bikes are available in different frame sizes:

• Curt: Small (50 cm), Medium (54 cm), Large (58 cm)
• Stout: Medium (54 cm), Large (58 cm)
