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.

To be honest, I wouldn't normally consider a kit such as the Cytronex C1, preferring to buy a fully integrated e-bike. But with supply problems of these at the start of 2021, I decided to go ahead. Cytronex exceeded my expectations, being really helpful in discussing the options I wanted and supplying a well engineered and thought out kit to attach to one of my existing bikes. Everything fitted first time and worked perfectly. Being able to customise the power levels using the App. is a great feature. I tend to use the assistance to get me over the hills and through the headwinds and normally only use the low setting which I have at 20%. With this I have found my rides so much more enjoyable and I ride further. Using it this way the battery lasts well. eg. after a 50m hilly ride, I had over 50% left. One of my fears was having to disassemble the front wheel to fix a puncture on the road. But having fitted the kit myself and being familiar with it, even this was straightforward. (I did remember my 17mm spanner!). This is really great product and excellent value for money. Recommended. Update June 2022. My Cytronex kit has now had its first birthday and everything I said originally remains correct. I've enjoyed the e-bike so much I decided to buy a fully integrated e-bike from a well known manufacturer, mainly as I fancied something a little more modern looking and stylish. However, I can say that aside from the style aspect, my Cytronex bike performs equally as well from a performance point of view and I may actually prefer the dynamics of having a front hub motor as opposed to the a rear hub. Being fortunate to have the two e bikes, the Tifosi/Cytronex was 'winterised' at the start of 2022 (and the more expensive new bike, kept for the better weather.) and it performed faultlessly through some pretty awful weather.

Great system. Adding the converter kit to her road bike (which I did quite easily) has made the difference between my wife never riding again and riding over 2000 miles this year. Has worked wonders for her confidence and enjoyment because she no longer has to worry about getting up hills or completing the rides. Thank you.

I love this Cytronex C1 kit. It's high quality, well thought out and has more than met my expectations. It was easy to install and the queries I had before purchasing were dealt with by Cytronex and their very friendly and helpful staff in a timely manner. As a direct result I am out on my bike everyday and travelling further and further. The electric assistance comes in smoothly and it still feels like I'm riding my own bike. It's also completely legal in the UK too and made by the guys in the UK.... This was important to me rather than buying a cheap inferior product that seem to be rife on the internet these days. I'm generally doing rides of about 25 miles and feeling fitter as i put as much or as little of my own effort in dependent on my mood. It's superb when it comes to hills, I don't need to put much effort in, perfect. Hills and cycling into a strong head wind I always hated, now I just smile a lot as I can have Cytronex kick in when I most need it.
