The Law
BS EN15194 is the official standard for electric bicycles in Europe, the UK will shortly adopt this standard - all Kudos bicycles already have been tested and comply with this standard.

To remain exempt from motor vehicle legislation an electric bicycle must comply with the following:
  • Maximum rated motor power 250 watts
  • Maximum power assisted speed 15.5mph (25kmh)
  • Power to the motor is cut when brakes are applied
  • Power only available when pedals are turning
  • Maximum bike weight 40 kilos
  • E-bike riders must be 14 years old
This allows an electric bicycle to be treated just as a conventional bicycle - they can ride on cycle tracks but do not require compulsory registration, insurance or MOT - for legislation purposes consider them as a normal bicycle.

How much is the cost of a replacement battery?

A big factor when considering the long term ownership costs of an electric bicycle. The most popular battery fitted to e-bikes has been lithium manganese (LiMnO4), this has an average recharge limit of 500 cycles (say, 2 years). Current cost is averaging about £300 but extreme examples can be £1000 plus.  All Kudos cycles, unless stated otherwise, are fitted with the latest lithium iron phosphate battery (LiFePO4) which are cheaper to replace (current average price £210.00 incl 20% VAT) and may have a recharge limit of over 1500 cycles (say, 5 years). They also have a very low self discharge rate, even when left unused. 

Our new lightweight performance bikes (Secret, Cobra, Tornado, Arriba & the latest crank drive) will use LiMnO4 to take advantage of the increased energy density (lighter weight) of that type of battery, however customers must appreciate this may be at the expense of reduced cycle life. Replacement cost will still be a reasonable £200.  Some manufacturers are now using compound cathode polymer batteries which is clamied 800-1100 recharges. The average cost seems to be about £350, we consider this currently to be an unacceptably high replacement cost but may review in the future.



[Back To Top]
What is the life of the battery?
Kudos Cycles currently (November 2012) use either LiFePO4 or LiMnO4 batteries. The best of the lithium manganese batteries lose at least 10% of their capacity over 2 years and the degradation is rapid after that period. Whereas LiFePO4 batteries have been shown to lose only 2% of their capacity over 2 years and the degradation afterwards is very slow. 

If lightweight is not a priority then LiFePO4 is the prefered selection, it is fast to recharge, offers full power until completely discharged and exhibits high discharge rate capability when required. On disposal, perhaps after 5 years, LiFePO4 does not contain any toxic heavy metals such as lead or cadmium nor any corrosive acids or akalines making LiFePO4 the most environmentally friendly battery chemistry available.

[Back To Top]
What is the range of the battery?

The range that can be achieved is based upon a number of variables, including battery capacity, rider weight, headwinds, flat or hilly and how much power via the crank pedal the rider is prepared to input. However, based upon average conditions, the following miles should be achievable.

9AH/10AH battery - 27-30 miles

Our updated 'Rule of thumb' is 3 miles per AH

Don't forget, unlike an electric car, if you exceed the battery range you always have the knowledge that you can pedal home.

[Back To Top]
What is the weight of the cycle?
The weight of the Kudos bicycles are stated in each product description. Generally the urban bikes (City, Lady and Commuter) are built heavier and tougher. Whereas the mountain and touring bikes are generally lighter - our Tourer at 21.30kgs is a particularly light cycle.

[Back To Top]
Are e-bikes safer than conventional bikes?
Electric bikes are easier to ride than conventional bikes, the rider is less tired and more alert. Power assistance can stop you 'wobbling' on hills and allows you to more closely match the speed of other traffic. To pull away from standstill with rapid acceleration can be a big advantage on a fast busy junction - at a busy roundabout this can be a real life saver.

Having the big battery capacity allows the use of powerful 36v LED front and rear lights, to see and be seen.

[Back To Top]
Do I need a licence, road tax, MOT or insurance?
You do not compulsorily need any of these, but it may be sensible to insure your e-bike against theft and third party public liability - this is often covered by your house insurance but needs checking.

[Back To Top]
Do I need to wear a helmet?
Not compulsory, but is obviously a sensible safety precaution when riding any bicycle.

[Back To Top]
What is the legality of use?
All Kudos cycles are road and cycle path legal, the rider must be minimum 14 years old.

[Back To Top]
When does the power cut off?
  • When the bike exceeds 15.5mph (25kph)
  • When you stop pedalling
  • When you apply the brakes

How about spare parts?
Our parent company is Rally Design, established over 38 years, we have considerable experience in stocking and servicing imported product. Our initial spares stock is over £20K. Our bikes are all sourced from well respected and well financed large cycle manufacturers who have extensive R&D and quality control facilities. However, like any mechanical/electrical product it can go wrong - we have a spare part for every bespoke part likely to fail, we will price spares fairly. For normal consumables like tyres, brake blocks and cables, these are mainly Shimano stock product available from most bike shops but if you prefer you can buy from our on-line shop.

[Back To Top]
Can I buy a kit to convert my conventional bike to power assist?
Yes, you can, but it is questionable whether it is financially worthwhile. The price of the battery, motor and controller/sensors is such a large percentage of the total cost of the bike and Asian assembly labour costs are so low that the effort is just not worthwhile.

Whilst writing this reply, I am looking at a hub kit from one of the popular UK e-bike suppliers priced £850.00+VAT, total £1020.00. That is more expensive than my top of the range Tourer, King or Commuter bicycle.

[Back To Top]
Can I buy batteries & spare parts to service my e-bike even if not supplied by Kudos?
Yes, of course, however you must ensure that the battery will fit in your current frame and that all parts are compatible with our components on your cycle - it is particularly important to note whether your cycle is wired 24v or 36v. We realise our average £200.00 inc. VAT battery price is very competitive - let's hope it acts as a catalyst for other e-bike suppliers to be more realistic when pricing replacement batteries, Kudos would welcome a fairer pricing structure.

[Back To Top]
Why are your bikes so much cheaper?
We buy in considerable bulk direct from the manufacturer and sell direct to the consumer, there are no expensive 'middle men' in the supply chain - these agents can add 60% to the bike's price, a £945.00 cycle from Kudos would be £1500 in a 'high end' agent.

However, we do sell through agents, but only those who appreciate that the profit margin needs to be reasonable so as to maintain a competitive retail price.

[Back To Top]
Your bikes are cheap but also highly spec'd?
The savings revealed by bulk buying were fed back into the bicycle to ensure that the specification, quality and style matches that of the top quality German and Dutch cycles. We don't sell cheap low quality cycles, we sell top quality cycles at a mid range price.

[Back To Top]
Are your bikes made in China?
Yes, as are many of the e-bikes in the world. Even the 'high end' manufacturers sometimes buy their frames in China. The Chinese now have manufacturers dedicated only to export markets - quite frankly these factories are too high quality and too expensive for the Chinese domestic market, but they understand the requirements of the European market.

Some of the mainland Europe manufacturers try to disguise the origin of the cycle and/or its parts. We think this is dishonest, Kudos will always declare the country of origin if asked.

[Back To Top]
I have seen an e-bike for £490.00?
This will certainly have been made in Asia. It must be understood that these Chinese manufacturers should correctly be called assemblers - they rarely manufacture anything in house, all parts manufactured are contracted out, they will build a bike to the price level you are prepared to pay. So a £490.00 bike will be the sum of the cheapest materials and parts available. This is one product that at the supply end you definitely 'get what you pay for'.

[Back To Top]
Kudos, here today - gone tomorrow?
No, we are committed to this product for the long term - it required an extension to our warehouse to accommodate the 700 plus opening stock - also we have committed to £20k supporting stock of spare parts. Our parent company, Rally Design Ltd, has been established 38 years. However, we are still a family owned and run business.

Regenerative Controller
In my opinion, marketing hype! The small amount of energy that can be regenerated in braking or downhill charging just does not seem worth all the extra equipment and cost.

[Back To Top]
Twist & Go
The use of twist grip throttle to provide power without pedalling would seem to be in contravention of European regulations and are only legal in the UK under the 1982 EAPC regulations. However, at a recent trade bike show in Holland I was advised that it is legal as a special licence costing £40.00 per cycle. In typical Government style, they have managed to create confusion out of simplicity. On this one I suggest you do your own homework.

Some of our bikes have 'twist & go' facility but disconnected - I suggest you only reconnect when legal to do so.

[Back To Top]
What happens if I lose my keys?
Each Kudos cycle is supplied with (2) keys to suit the battery/ignition system, plus where fitted the anti theft lock.

It is very important that you keep the spare keys safe.  We regret that it will not be possible for us to issue replacements even if the key number is known.

It is strongly suggested that you have spare keys cut and keep these in a safe place.
