Highlights Spectral:ONfly CF 8
More control. More fun.
We’ve equipped each Spectral:ONfly with K.I.S.—an ingenious spring mechanism housed inside the top tube that helps center your steering. End result? You experience more control on sketchy descents, more grip when its loose, and more fun in rough, off-camber conditions.Fine tune your handling
You can custom tune how K.I.S. feels—with a simple twist of an allen wrench—to suit your own ride style and conditions. What’s more, K.I.S. is totally maintenance-free, protected from damage, and has a lifetime warranty. Don’t fancy K.I.S.? Each bike comes with an easy to install blanking plate that covers the adjuster slot.What is :ONfly?
:ONfly is our line of innovative, lightweight e-bikes that range from e-MTB to e-gravel machines. Featuring sleek, compact motors and batteries, our :ONfly models hit the elusive sweetspot between traditional bikes and full power e-bikes.CLLCTV approved
“Wait, this is an e-bike? There were multiple moments on the trail when I forgot I was riding an E-MTB. The bike feels super playful and lightweight. It’s nice to just pedal and not worry about how hard you are working.” — Samantha Soriano, Professional Freeride MTB athlete.Key features

Bike classification
This category also covers the requirements of categories 1e-3e. In addition, bicycles of this category are suitable for very rough and partly blocked terrain with steep slopes and higher speeds as a result thereof. Regular, moderate jumps by experienced riders are no problem for these bicycles. The regular and durable use of the bicycles on North Shore trails and in bike parks should, however, be excluded. Due to the higher stresses, these bicycles should be checked for possible damage after every ride. Full suspension bikes with medium suspension travel are typical for this category. The E-Bike specific information is mentioned on the CE marking on your bike.
Bikes in this category provide motorised support up to 25 kph. You can ride above 25 kph, just without support.
