Cannondale Synapse looks like the future of cycling

The cycling world is rather conservative in many ways, and new developments do not come along very often. Most cyclists have only recently started to accept that ebikes, for instance, are not an abomination before the Lord, and deserving of shunning if not outright banning. So Cannondale is taking a bit of a bold step with the latest version of its versatile and comfortable (by road bike standards) Synapse road bike. 

Selected versions of the fifth generation Synapse come with an integrated battery pack and the all-new SmartSense system. This isn’t to power the bike along. SmartSense instead powers core bike features that would previously all have to be fitted separately and run off their own individual batteries. For version 1.0 of SmartSense, Cannondale has just stuck to lighting and a rear radar system to warn you of oncoming traffic, but the potential uses of such a system are obviously much wider. If the conservative cycling market will accept the idea of instantly upping the headline weight of their bike by bolting a battery to it. 

A lot of the best ebikes, aimed at a techy, hipster market are already more or less smartphones on wheels. You’ve got the Angell ebike with its built in lock and alarm system, GoCycle G4i with its traction control and lighting, and VanMoof S3, which pioneered the app-controlled, multi-functional commuter bike. There are ebikes with crash detection that can contact the emergency services, ones with automatic gearing, ones with advanced screens built in. There are all manner of techno innovations that could eventually make their way to standard bikes via SmartSense or a system like it.

As I say, in the case of the Synapse, the feature set has actually been kept deliberately quite short. However, there are ideas familiar to ebike users, such as using the Bluetooth on your phone, once it has Cannondale’s app on it, to power the bike on as you approach it. So the integrated Lezyne lights turn on, the radar – a variation of Gamrin’s Varia system – powers up, and you’re ready to go. 

The lights are designed to be used all day, and can adapt to ambient lighting conditions. So during daylight, they just provide a little extra visibility – always welcome – without draining the battery pack too much. But if you go into a tunnel, or as night falls, the focussed beam boosts up to its full 350 lumens. 

The Varia rear radar system is another great safety system. I must admit, when cycling I am perfectly happy to either look over my shoulder or largely ignore what’s going on behind me. However, I can see that a radar system would be extremely appealing to a lot of riders. It’s also probably the kind of thing where, once you start using a Varia radar, you never want to go back to not using one.

The Varia scans for rear approaching traffic with its radar eye, and alerts you via a system of beeps and lights on the head unit if anything is drawing too near. Apparently it can even tell you how many vehicles are bearing down on you, and at what speed. This could be useful in preventing accidents but it is probably more useful for general reassurance. It could help make car owners feel more loved, if you are cycling side-by-side with a pal, and use the radar as a cue to move back to single file. Your good deed for the day. 

For now, that is the extent of the SmartSense system’s powers. However there are junction boxes on its integrated wiring that could be used to add further devices – bike computers being the obvious example. 

I could see this system really coming to fruition on a more urban-commuter kind of bike, where keeping the weight down is less of an obsession. As it stands, the battery is only enough to power everything for a few hours, so you will have to charge it every day – admittedly this is not a huge hardship. Interestingly, you can’t use it as the main or even backup battery for Di2 electronic gear shifting, if you go for that option.

Cannondale says that the integrated power supply means the lights and radar weigh 35g less than if you installed it all separately, so that is a good plus point for the MAMILs.

None of this would matter much if the Synapse wasn’t also a great bike to ride, but it is. Our chums at Cycling Weekly took it for a first ride recently and they seemed to like it. This bike builds on 15 years of learnings from the Synapse lineage and while the idea of a road bike that is actually comfortable to ride is no longer a mind-blowing one, I have no doubt that the Synapse is a lot of fun to ride, and also no doubt able to shift like a slippery eel when it’s required to, and get you up hills sans cardiac arrest. 

Simon Smythe of Cycling Weekly was most impressed by SmartSense, however, calling it ‘a game changer’, no less. I agree that there is huge potential in this idea and I can’t wait to see where Cannondale takes it in the years to come.
