Kalkhoff Image L Season Review

German precision engineering for the vertically blessed.

The Kalkhoff Image L Season proves that lightweight ebikes don’t have to sacrifice sizing options. Available in XL for riders up to 6’5″ (196cm), this German-engineered city bike delivers premium Bosch performance in a package that finally fits taller riders properly.

Kalkhoff’s attention to geometry shows in the numbers. The XL frame provides proper reach and stack measurements that create a comfortable, upright riding position for tall riders without the cramped feeling that plagues most city ebikes. The 29″ wheels (650b) work perfectly with the longer wheelbase, providing stability and rollover capability that shorter wheels can’t match for taller, heavier riders.

Give it a good Bosch

The Bosch Performance Line SX motor represents the latest thinking in lightweight ebike systems. At 250W with 60Nm of torque, it’s not chasing maximum power numbers – it’s optimizing efficiency and natural feel. The Smart System integration means seamless smartphone connectivity, ride tracking, and over-the-air updates that keep your bike current. This is premium German engineering where every component serves a purpose.

What really sets the Image L Season apart is the weight. At approximately 24-25kg with battery, this is genuinely light for a full-featured ebike, especially one available in sizes for tall riders. That weight difference matters when you’re lifting the bike onto storage hooks, carrying it up stairs, or just maneuvering in tight spaces. The CompactTube battery contributes to the low weight while still providing 400Wh capacity for up to 80km range.

The right bits and pieces

The 7-speed Shimano Nexus hub gear system is brilliantly matched to urban riding. Low maintenance, protected internals, and the ability to shift while stopped make city navigation effortless. Combined with the KMC Z1 chain and 38/19 gear ratio, you get efficient pedaling across the speed range without maintenance headaches. The Suntour XCM32 fork with 50mm travel and lockout capability absorbs city bumps while providing rigid efficiency when you want it.

Hydraulic disc brakes with 160mm rotors provide confident stopping power, while the Schwalbe Big Ben tires (55-622) offer excellent grip and puncture resistance. The MIK rear carrier handles 25kg of cargo, making this a genuine workhorse for commuting or shopping. Integrated Herrmans LED lights front and rear, full plastic mudguards, and an adjustable kickstand show Kalkhoff’s attention to practical details.
