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.

I have fitted Cytronex C1kits to two of my bikes – a Raleigh titanium-framed model from circa 2000, and a Colnago Master X-light from the mid-1980s. The kit components appear high quality - the only exception is possibly the power switch which appears to be a little flimsy. The fitting instructions are generally excellent. I had one issue with fitting of both kits: the tab washers supplied to fit forks with safety lips did not fit flush with the fork blades, and needed a few minutes attention with a file to allow them to seat properly. Be aware that with rim brakes, the calipers will need adjusting if the replacement wheel is a different rim width to the original. Another adjustment, which puzzled me at first and is less obvious, is the brake block height may need lowering. This is because the replacement wheel sits slightly lower in the forks than a standard wheel. I recall seeing mention of this in the instructions for Brompton bike kits, but not in the instructions for ‘conventional’ kits. In use, I was impressed by the performance. I didn’t notice the extra weight at all – bike handling seemed unchanged (I’m a 78kg rider). I generally ride with the power permanently on its lowest setting, using an occasional boost to mid-setting for steep hills (+6% or more for me), and according to the battery bottle colour code, I’m using 50% capacity for around 25 miles. One issue I’ve noticed is with the power switch, which I find is too easy to switch off instead of changing power levels - disconcerting when you are struggling up a hill and attempt to increase power and switch off instead! If the ‘power off’ command was set to require a 'long' push - as is common with similar electronic devices - this issue would be resolved. I’ve contacted Cytronex twice with queries, and I’m very impressed with their speed of response. Bear this in mind if you’re considering a purchase of a similar system from another supplier…

Fantastic piece of kit. Just returned from 22 mile round trip (Winchester-Alresford and back) (intermittent use of power) and still have 50% of battery capacity. Has got me back on a bike and cycling which I loved after five cardiac ops, a femoral aneurysm in my right leg and a prostate op (call me lucky!). Very well designed and thought through equipment, and fantastic customer care at Winchester shop. Couldn't recommend more highly.

The Cytronex system is an absolutely excellent upgrade for those that want to keep their current bike, but really want the benefits of an ebike. I spent some time looking at various solutions on the market and ultimately chose Cytronex due to its functionality, aesthetics, and friendly but professional pre and post sales service level Jake and the team provided. "You get what you pay for", this certainly is the case in this instance and I can wholeheartedly say you will not be disappointed in the quality and performance this system.
