Keep us informed please. I don't know how to repair the bikes when they go wrong. As I can't I am interested in the shop servicing record. Raleigh is not all it is cracked up to be with the Raleigh Motus either (hearsay). One of the rival shops in Shoreham: 50Cycles, Halford, Giant or Raleigh to chose from. (I think these all repair the ebikes they sell?)
.. Persus you made this negative comment about the Raleigh Motus before and I questioned you on it, to which you did not respond. Please advise what was the nature of the negativity in respect of this product. As I have stated on I think three separate occasions, to you I have this product and I am very pleased with it.
Thank you

Seems to me Perseus has a very cautious attitude to risk.

Nothing wrong with that, but all his reliability concerns can never be satisfied.

In that respect, I don't think any ebike is for him.

Hi All,

Our trip to Majorca this week may help persuade Perseus that it is now the best time to by an ebike.

It is a buyers market with regards to choice, style, power, range and fun.

To build the market in the UK we need to embrace the positives of all the brands out there now making ace electric bikes. As everything nowaday we are simply spoilt for choice and life is sometimes too easy compared to 14 years ago when bike shops would laugh you out of the shops and customers would comment that they could buy a small car for the price of a decent far east electric bike.

Times have changed the market is healthily competitive giving the consumer the greatest choice ever at the best price to value ratio even within the conventional bike sector when we look at the really high end components.

Kind regards

Scott

Not really meant to be a negative comment, just to show that any ebike can go wrong, Raleigh just as likely as Kalkhoff, or Bosch as Impulse. I am going to get advice from someone who had an ebike for 10 years or more w/o any trouble and sold for more than he paid for it working. 19 out of the other 20 have had various problems though. And I think all of them in the first year whatever model. No details of the fault. Just doesn't work. Like my Cyclamatic.

PS: what do cyclists do about insurance? Will the household policy pay out if the bike is stolen or vandalised. Mine wouldn't be damage on property of ordinary bicycles.

i have a 2014 haibike bought off ebay as got sick of the dealers bs and only ebike shop will honer the warranty with a dongle fitted.:rolleyes:

so i bought one off ebay a £5500 rrp bike with 160 miles for £3500.

it has over 3000 miles on it now and i hammer the crap out of it and a dongle fitted since day 1.

i have broke a xd hub and had it replaced buy crank brothers as it had a 2 year warranty stamped on it so not much choice.

and lost one frame bolt 25 quid.

the rest are held in place with cable ties ;)

I realy miss the 17ah battery that i had on the Focus with the impulse motor because in high power mode i could get 50 miles range.Now i have the Bosch CX with the 500wh battery i`m lucky to get 28 miles out of it.(same tyres,power mode and weight)
Bosch realy need to up their game with the batteries they provide.

I regularly get 50-55 miles on maximum power output from my 500wh Bosch. Mine isn't the CX, though so perhaps that is the difference.

The Focus was S class and the Bosch cx has no speed limiter just to clarify so average speed would be around 24mph on both.

I'm sure they can but along with that they would up their prices as well :eek:.

It's true, of all motorised vehicles, e-bikes are the least reliable. Even a cheap light motorcycle or scooter is far more reliable and often very much cheaper to run.

Even on one like the highly thought of old Giant Lafree with the Panasonic crank unit which was mostly electrically reliable (though not entirely), there were the wear problems of chains and sprockets and brake blocks, the odd gear hub failures, cables seizing up, crank arms coming loose, regular punctures, internal freewheel locking up etc.

The only reasons to buy an e-bike instead of any other powered two wheeler is if one wants to pedal as well, or wants to use cyclepaths. Otherwise, forget e-bikes.

You forgot to mention that it makes you smile like an idiot all day long
All part of the pedalling enjoyment that cyclists can have. I probably should have said "if one wants to cycle" rather than "if one wants to pedal".

... I sorry Persus, but that is not good enough, I have looked on line particularly to search for negative comments attributed to the Motus and have found none. You have indicated on two occasions " hearsay" about this bike .

Is there any manufactured product that 10 years after purchase is more valuable than the initial price? ....With the possible exception of a piece of fine art or astute property purchase .
An electric bike, like any other product is bought o be used, it needs repair and maintenance. You can expect punctures, bent wheels blown bulbs, rust and chain repairs. With an electric bike you can also expect gradual deterioration of the battery pack. You have a right to expect years of use from the motor and the frame. You have no right to expect maintained free, service free operation for years on end. .. Even if you never used the thing and left it in your hall in its new state, the tyres will perish after 5 to 6 years.

You need to be truthful to yourself as to what you expect and be realistic. I understand once bitten twice shy, but are you even sure your old Cyclamatic is truely defunct?. It's only a machine and has only so many parts, so if the defective parts are replaced or repaired it will work. It may not be economic to repair, but that is a value judgement, not an engineering imperative.

The bosch cx system is good but let down by poor battery capacity.Riese and muller have tried to get round it by fitting a two bosch 500w battery system that looks ridiculous.
Kalkhoff have always fitted higher capacity batteries than most of the other e-bike manufacturers.

... I anticipate that battery capacity will periodicallyincrease while retaining the same price structure. There will be better and higher capacity chemistries

Pedal bicycles (new price say £400 before discounts) are quite cheap to run. After a year the chain will stretch with derailleur (quicker with ebikes, 6 months?), cables will need to be replaced (fiddly), break blocks might wear out (good ones available). I used to fix this myself but now I like to take it in for a service. Running costs are extra food intake for energy expended. After five years or so back wheels might need to be replaced, and odds on there will be a mishap involving damage. This is expected.

Summary: in short, a hub geared bike and a shop that will annually service an ebike is a real bonus. I would not pick a hub motor ebike again. Still got to look at my Cyclamatic as I don't know what is wrong with it?

The salesmen always manage to put me off ebikes. The merits when they work they keep on repeating are well known. What to do when they go wrong is less certain. All the cheap ebikes (under £1000) seem to go wrong in under a year, the ones in the range to £2300 have minor problems not worth mentioning in the first year but not sure after 2 years, and the ones over £3000 seem to not report problems at all.

Another thing I have found is that range that the ebikes do is overstated by about double on the cheap models.

I want an ebike for the hills with lots of local cyclepaths and dangerous roads for mopeds. I really want a throttle as my knee could be painful at any time because of arthritis. Pedaling is good but once already it has become too painful and the prognosis in poor (X-rays say).

I think that a throttle really needs a hub motor. Have a look at a Wisper. I believe the throttle works as long as some pedaling is done but you can get someone to over ride this. My Wisper is 3 years old and still going strong.

Thanks Crockers! Yes our throttle works to 15.5mph as long as the pedals are turning.

Alistair from Atmosphere in Bristol sent me an image of this 905xc Tourer our carbon matrix bike sold in 2010. Still perfect with the original battery after 6 years. Just goes to show paying a little bit more for a hub motor bike and having your ebike regularly serviced pays excellent dividends.
