inspired by the animal kingdom’s sleek and powerful black panther, calamus one ultrabike represents the latest innovations for e-bike technology. it creates a new category for electric bikes, the ultrabike, powered by ultra-drive mid-motors from bafang, and driven by carbon belts from gates, making the vehicle ultra-responsive. additionally, the bike is highly efficient: enabling up to 70kms of range on a single charge, including a quick-charge option, and featuring a detachable battery.
the calamus bike includes an integrated weather-proof computer and navigation touchscreen, being the only e-bike to offer support for android apps, rider profiles and real-time self-diagnosis. it’s also the first bike equipped with ultrasonic sensors that scan your blind spots, and handle grips that vibrate to warn the user about approaching vehicles. the ultra-bike frames are custom-casted unibodies with 100% internal cabling. this gives the bike a sleek, bespoke look, with unbroken contours throughout the body.

by following the concept of ‘form follows function’, the bike’s modern and minimalist aesthetic follows the top-tier features it includes. the designer’s aim was to make the bike as user-centric as possible, ‘we had to make sure that the frame geometry, riding posture, safety, connectivity and theft proof features were integrated into one beautifully crafted package.’
calamus one’s cockpit is where you will find all the necessary information – bike diagnostics, controls, navigation, etc.

I have build 4 electric bikes for my own usage (nexus 8 and 11 gearbox, NineContinent and Bafang engine, Carbon belt). I love the frame with integrated battery and carbone belt. I don’t understand 48 voltage choice because of risk to distroy the gearbox with too much torck ? You high level of electronics systems will be a true added value if It is able to better « assisting manual shifting gear »: today this is a problem on electric bike with Shimano Nexus gear box! But I want to shift manualy gears ! I am not waiting for to much electronics systems on a bike except very good light system.
*This bike is very aesthetically appealing, unless you want the same ol same ol.
*Fenders, rear rack, AND front rack are offered as very low cost options, with some included as stretch goals.
*There is a hidden electrically operated mechanical lock, various alarm settings, mobile phone alert, fencing programing, and 4G GSM global tracking. In other words, everything but a doberman and a Pinkerman Guard. More security than my $10K Stromer, or any other bike available today.
*The performance is right at the legal limit; 28mph and a 750 watt motor for the US, and other regions are sold within local regulations. Performance is not just horsepower, it is also torque. Calamus has a whoping 160Nm of torque. Stromer hasn’t broken the 50Nm figure yet, and Trek, R&M, and others using the Bosch system have 63Nm of torque. To say “the performance isn’t any better compared to some bikes on the market already” is an unresearched, unsubstantiated statement. The Calamus has over twice the performance.
*Stated range and actual range are often not near the same. A mid-drive will always outperform a hub drive in range (watts per mile), and the weight of the bike is a factor also. Calamus wins here.
*If you are looking for “simply technology masturbation”, there are other sites for that. Calamus is the Real Deal.
the design is quite sleek, the performance isn’t any better compared to some bikes on the market already, especially the range is just below moderate.
I look forward to see calamus in folding model
Apart from not finding this bike aesthetically appealing, I’m tired of designs leaving out essential features, such as mudguards and a porter. It’s simply unfit for everyday use. One of the biggest issues with premium bikes in urban areas is theft and I expect from a designer to also take those issues into consideration. There are so many designs out there that are simply technology masturbation and completely ignore what would actually make a bike for for real life.
