The 10 best compact e-bikes of 2021
I:SY DriveE
The i:SY DrivE is one of the pioneers among compact e-bikes. Little has changed in the proven overall concept with 20-inch wheels and the size-variable, very stiff aluminum frame - why should it? The bike now has a large and constantly growing fan base. The character of the i:SY can be determined by the equipment; it is available with the entire range of Bosch drives, from the comfortable Active Line to the lively, powerful CX and the S-Pedelec Motor Speed.
Price: 2.799 euros – 5.199 euros
Hercules Futura Fold
The additional weight of the motor and battery is more noticeable in hardly any other category of bike than in a folding bike, which is regularly lifted. Hercules has taken on this problem with the new Futura Fold Carbon - here a carbon fiber frame meets the light Fazua drive innovatively integrated in the seat tube. The Futura Carbon, which also looks very elegant, is certainly one of the lightest e-folding bikes on the market. Nice: Hercules offers numerous equipment variants, with derailleur or hub gears, the latter even with a back pedal.
Price: 3.499 euros – 5.999 euros

Kettler Family
With the Familiano, Kettler has succeeded in bridging the gap between compact bike and cargo bike. The wheelbase of the Bosch e-bike, even in its long version with space for two kids on the luggage rack, is no longer than that of a regular bike - thanks to 20-inch wheels. With a permissible total weight of 180 kg, it is not only prepared as a children's transporter, but also for larger loads.
Price: 3.999 euros – 4.7999 euros

Testing the Kettler Familiano e-bike: The child carrier
Kettler Familiano LN: The traditional manufacturer Kettler Alu-Rad is presenting a modern, well-designed cargo bike that is aimed specifically at young parents, but is also tailored to transporting loads. Highlights are the high permissible total weight and the powerful motor with a double battery and thus a long range. Anyone who treated their little children ten, fifteen years ago with the […]
Corratec LifeS
Not boring at all: The bright Corratec LifeS brings color to the often somewhat stuffy category of compact bikes. However, this is not only due to the countless color combinations themselves, but also to the general design language somewhere between retro bike and chopper. With its thick balloon tires and the upright seating position, comfort is not neglected either. The stylish cruiser is powered by a Bosch Active Line or Active Line Plus motor.
Price: 2.599 euros – 2.799 euros
Cube Compact Hybrid
The Compact Hybrid is a stylish, practical and above all fun companion for the urban jungle. The stiff frame, in conjunction with the 20 inch wheels and the Bosch Performance motor, leads to a lively driving experience, which, however, does not lack the necessary smoothness. Thanks to its long seat post and the variable cockpit, the bike can also be adjusted to different body sizes in a flash.
Price: € 2.499

Flyer Upstreet1
With the Upstreet1, the e-bike specialists at Flyer are launching one of the most comfortable compact e-bikes into the season. Not only the pleasingly low step-through speaks for this, but also the large-volume tires and the spring support installed in all equipment variants. Either a Bosch Active Line Plus or Performance drive provides support so that things move quickly despite all the comfort. Positive: The motors combined with a 500 Wh battery are among the quietest on the market.
Price: 3.499 euros – 3.999 euros
Tern GSD
The GSD is Tern's contribution to the growing category of compact cargo bikes. With the 20 inch wheels, the bike remains nice and compact and yet has a generous maximum system weight of 200 kg. The specially developed center stand allows convenient loading without having to hold the bike. Clever: The luggage rack allows upright and space-saving "parking" within your own four walls. The enormously powerful Bosch Cargo Line drive also ensures that you reach your destination comfortably, even when fully loaded.
Price: 4.699 euros – 8.299 euros
Vinora Radius
The puristic Radius can set itself apart from other compact bikes simply by the choice of drive system. Winora relies on the very reliable and, with a maximum of 70 Nm, also quite powerful Yamaha PW-ST motor in connection with a 500 Wh battery. With the folding pedals and handlebars that can be rotated by 90°, it can also be stored in a very space-saving manner - whether in the garage or in the apartment.
Price: € 2.799
Kettler Quadriga Cityhopper
With the Cityhopper, traditional manufacturer Kettler has reduced its popular Quadriga series to compact wheel dimensions. The small wheels and the Active Line Plus drive give the visually very successful bike a lively, but not nervous character. The cleverly designed frame offers a pleasantly low step-through and can be quickly adjusted to different body sizes by pulling out the support and handlebars. If you don't have much storage space, you'll appreciate the foldable pedals and rotating handlebars.
Price: € 2.999

The 330 Wh battery is disguised as a handlebar bag and can be removed with a flick of the wrist.
