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.

07 CHARGER

Compact Fast Chargers with Charge Progress Indicator

To charge – turn your bottle upside down and place in the charge shoe. The bottle LED will shine on the Cytronex logo to indicate charge level as charging progresses – if you are in a hurry you can see when you have enough charge for your journey.

Our compact fast chargers and charge indication function are perfect for topping up your battery when you stop for lunch or coffee – the Standard Charger will re-charge about 80% of battery capacity in 2 hours and the Fast Charger will do this in about 1 hour from empty.

It is not an exaggeration to say that adding a Cytronex C1 hub to my bike has been a total revelation for me. My cycle route to work is 50km and includes 800m of climbing each way. I used to commute by bike maybe once a year to remind myself I could still do it and it would leave me ruined, now I am doing it twice a week, 20% quicker and at the end of the day I still feel fresh. The battery easily lasts the full 50km even when set to give a hefty boost on the climbs and into headwinds. The kit is easy to fit, a total pleasure to use and really nicely made. In my (admittedly limited) experience adding a C1 motor to your favourite bike will be much superior to and certainly cheaper than something equipped with a bosch/shimano/yamaha motor and it will probably be about 3-5kg lighter too. I strongly recommend the Cytronex C1 motor to anyone who'd like a boost to their own leg power or simply wants to go further.

The new Cytronex C1 is a wonderful piece of kit and inside 1 hour converts your bicycle into a very light, manageable electric bike. Best of all it upgrades your favourite bike. In 2012 my wife purchased a Cytronex Legacy bike. The following year I also purchased a Cannondale fitted with their system. Between us we have ridden over 15,000 miles. Sadly in late April 2022 my system died altogether and I was faced with cycling the Coast 2 Coast without assistance. A call to Jake at Cytronex and he assured me all will be well. The new kit arrived in three days, which is remarkable given supply issues in the rest of the industry. Within an hour it was fitted to my very dear Cannondale. 8 days later the four of us were in Whitehaven ready to start our journey across the United Kingdom to Tynemouth. A total of 140 miles and many thousands of feet of climb. The C1 performed very well and I managed to keep up with my wife on her Legacy bike and our two friends on their Raleigh Motus bikes. If you have one of the original Cytronex systems then I can thoroughly recommend the upgrade. It is: > easy to fit (adjusting the speed sensor is awkward) >the power rating has 5 settings so power usage can be conserved >the LED on the battery tells you how much energy you have left >the bluetooth app gives you detailed information about the condition of the battery >it comes with its own battery carrier with a provision for a padlock so one can leave the battery in situ and it is safe >it is a much simpler system without all the wiring and magnets of the old system >the new charger is smaller, lighter, simpler and it has a colour coding to inform you of the state of the charge Next year we are planning to cycle from Dieppe to Paris and I will be riding the Cannondale with the C1 again. What I will invest in before then is a Fast Charger to take on the road with me, just to boost the battery every time we stop for coffee and cake. Well worth the money and especially the satisfaction that serious bike users do not believe you own an Electric Bike! The system is very well crafted and unobtrusive.

My husband bought the C1 UK conversion kit, the process from start to finish was super easy, communication with Cytronex was always super fast and nothing was too much trouble for them when answering any questions. The kit came quicker that the expected date and was quick and straightforward to fit, the instructions were clear and easy to understand. The excellent service doesn’t stop at pre sale, post sale questions are answered just as quickly and almost immediately. It’s been an absolute pleasure to buy from Cytronex and my husband is over the moon with his kit. Thank you so much and if you are thinking about buying one, stop thinking and just do it, you won’t regret it, we can not rate them highly enough.
