01 EBIKE BOOST BUTTON

Fitting the Cytronex C1 electric bicycle conversion kit to a bicycle does not change the way the bike rides when the system is off, so when the terrain is easy, you don’t need assistance. When the going gets tough, just press the ebike Boost Button and smooth, refined and virtually silent assistance powers you up steep hills and through head winds. A Cytronex C1 assisted electric bike rides like no other electric bicycle.

Ebike Boost Button turns on and off with a single press. If you press and hold for one second the button will change colour and provide a different power level. You can set the power for each colour in the C1 App. Whatever power level you choose – your Cytronex ebike will add that precise power level to your cycling effort. Press and hold the ebike Boost Button for two seconds and you can turn on the optional high power LED bicycle lights. Read more

02C1 App

Customise your ride.

The Cytronex water bottle battery connects to your PC via USB whilst in the Charge Shoe so you can use the C1 App. This allows you to set exact power levels and the brightness of LEDs – day or night. The App includes a diagnostic function – in the event of an issue you can send a log file to Cytronex and you can update your system automatically when new software is available. The advanced all British electronics can maintain a precise power level so you can enjoy riding with family or friends. No other ebike does this.

05 CYTRONEX SENSOR

One Sensor, Low Maintenance, Easy fitting

Our multi patented Cytronex sensor replaces the 3 sensors required by other electric bike conversion kits to comply with regulations and fits quickly and easily without bicycle tools. Cytronex sensor detects the movement of a rear sprocket to monitor pedalling and bicycle speed on most bikes and the ultra fast response means a brake sensor is not required.

Sensor head swings out of the way if knocked during bicycle maintenance and can simply be flipped straight back to the original position.

06MOTOR

Discreet small and lightweight motor packs enough power to easily climb hills
and silently pass even the strongest riders.

Our new hub motor wheel is available in disc or V-brake versions, black or silver to match your rear wheel and a variety of sizes to fit your bike. Selecting European C1 provides 25Kmh maximum speed and the USA version has a maximum speed of 20mph. With Boost off, the motor hub is not engaged and the wheel spins freely without resistance. The motor weighs just 2Kg and the complete C1 conversion kit adds just 3.6Kg,- start with a good bicycle and the result is often 5Kg+ lighter than a purpose built electric bike.

As I approach the age of seventy with my formerly good knee now becoming the worse of the two, I was intrigued to watch Channel 5’s The Gadget Show feature on the C1 Cytronex e-bike conversion kit. It looked to be exactly what I needed to make life easier on the surprisingly hilly terrain in the Sussex Weald north of where I live. I duly made an appointment for a test ride at Cytronex’s shop in Winchester. I was received by the charming Sam who set me up with a smart Cannondale hybrid and she duly sent me off on the several handy hills nearby to test the mettle of the conversion. I was so impressed I soon placed an order for a kit to suit my trusty Claud Butler Voyager trekking/hybrid bike. Cytronex do offer new bikes fitted with the conversion or they can fit the kit on your existing bike for a fee. I opted for the DIY approach and, after providing several important measurements, the kit duly arrived tailor-made for my bike. The kit was beautifully packed and came with all instructions to help with fitting. As several have said before, fitting is relatively easy as long as you stick to the instructions, especially paying particular attention to the siting of the special sensor near the back sprocket set. Forty minutes is a rough estimate for the time it takes. After a week or so of riding, the beauty the system has fully revealed itself to me. Different levels of assistance can be switched on and off as needed and the extra weight still permits you to pedal unassisted even up gentle hills. In practice the lowest level of assistance is all you need for most trips and it can also be dispensed with altogether on the flat, or downhill. In this way I manage a total of 30 miles on two differing rides on one charge. The first had a total of 1100ft of ascent, using full assistance on a couple of short 20% hills but still leaving me with just under 50% battery life. On my next ride I managed a further 15 miles on flatter terrain which took me to under 5% battery. This is remarkable for a battery which is not one of the largest. The other advantage is that for short relatively flat trips the bike is perfectly rideable without assistance especially if you remove the battery from its mount, which saves 1.5kg of weight. You can easily replace the motorised front wheel with the original and revert completely should you so wish. The big plus with this system is that you are not tied to a heavy purpose built e-bike necessitating assistance being used at all times and with the danger, however remote, of being stranded away from home with a flat battery. Should the worst happen you would still be able to get home with relative ease. Nor does your bike look obviously like an e-bike. To the uncultured eye the bike looks like any “normal” bike with an extra large drinking bottle on the frame. This may not be the cheapest e-bike conversion kit but it is obviously a quality product with more than lives up to expectations.

First-class product and service I took the leap to buy a C1 kit encouraged by the excellent reviews Cytronex has gathered over years. I’m very happy to write a glowing review myself now, which might help someone else weighing up their decision. This is a big investment to most people, after all, and you want to know you’re getting it right. I bought a self-install C1 kit, having visited the Winchester showroom to double-check it could be fitted to my commuter bike, and to take a test ride of one of their stock bikes. The instructions were very clear to follow. I took my time—I like to have things neat—but nothing was particularly difficult (and my bike mechanic skills are not advanced). The trickiest thing was changing the tyre over to the new wheel, really. The gear sensor took some trial and error over 10 minutes to set it just so, but that wasn’t very difficult, and having set it, it hasn’t budged. I’ve used the kit on my daily commute (10km each way) for a couple of weeks. It’s fun. It does everything you think it should do, in the most natural way possible. The best analogy I can come up with is that it’s like a travelator at an airport: only when you step off the moving walkway do you realize how much you were moved along your way without thinking about it. For me, commuting across town, the two big wins are: (1) pulling away from stops that bit more promptly—which (a) feels safer and (b) reduces repeat pressure on my middle-aged knees—and then (2) gliding up hills like never before, thirty years younger or not (I just don’t like cycling up hills). There’s nothing to learn after the first few rides. The mechanics have all been refined by the designer to make the kit practically invisible in everyday use, and that’s exactly what you want. My contact with the company has also been handled very well: team members have been interested, responsive, knowledgeable. We had one snag with delivery to sort out, and that was taken up immediately and effectively. It’s only when something goes a bit awry that you can see whether the other person can recover and carry on—they managed all of that in a very human and professional way. So that’s my 10/10 review. I fully expect to be quietly chuckling to myself as I go about my commute for years to come, with luck. It’s a considerable small pleasure, and the company fully deserve their success. On the photos, you'll see a lot of cables on my front bars—but only one of those is for the Cytronex button; the other four are the cables for my brakes and gear shifts.
