welcome to the forum maestro,as you sound like a strong rider i think a panasonic powered bike would probably be most suitable, eg kalkhoff but these are not cheap at well over £1000,they ride much like a normal bike but are a bit heavier,i think the extra drag from a hub motor would not suit your needs, a bike such as a powacycle salisbury with 6 gears or so would take an awfull lot of effort to reach 25mph on the flat,also the drag from the hub motor can feel like sticking brakes on some bikes.

Bikes like the powacycle, and the others you mention are available locally, can't be derestricted. If you can cycle at 25 or even 20 mph on the flat on a normal bike, I think you will find most electric bikes unsuitable! Even on a Mark 1 Torq you will not be able to go that fast. You'll be spending most of your time above the assisted range, so you won't benefit from the power, and they will not be as pleasant to ride unpowered as your current bike. For example owners report that the Torq 1 provides good assistance to 22mph but is very hard to pedal faster than that due to factors such as motor resistance.

Good luck with your search, but I fear that, unless you are happy to go a lot slower than on your normal bike, you may not find an electric bike that meets your needs.
I agree a cheap e-bike like my 36v Li-ion Synergie G2 Mistral is not fast. However, it does come straight out-of-the-box de-restricted and will travel along the flat at 15+ mph on throttle alone carrying my weight 65 kg (10.5 stones) and has a range of at least 33 miles in pedelec mode. I heard one person rode for 20 miles on throttle alone on one charge!.. must have been flat country I would think. My average speed on a 33 mile round trip of hilly terrain was 12 mph. This is easy riding even for me at age 66 years but it's useless trying to race the hub motor.. it chooses it's own pace and like the Torq 1 quoted above "is very hard to pedal faster due to factors such as motor resistance". All this from an e-bike costing only £450.

Many popular electric bikes cost more than twice the price of my Mistral. Average speed is a very important factor for a commuter such as "The Maestro" to decide which electric bike to purchase.. anyone know if/where this speed information is posted?

The only place you'll find average speeds published for a range of e-bikes is in A to B's road tests, where they usually report them.

Of course it's not a reliable measure anyway, since so much depends on the rider's ability.

Thanks flecc.. I was just researching the question myself and found A to B's road tests. Your own website is also an invaluable resource for a guide to the performance on a range popular electric bikes.

As you say speed depends on many factors.. weight of rider.. age.. fitness.. wind speed etc.,


This is the information I found:

Powabyke: source A to B magazine
Assisted average speed - close to 15 mph

Torq (de-restricted): source 50cycles - extracts from A to B review
Assisted average speed - "flattish 9 mile" - 19.6 mph, pedalling with "reasonable enthusiasm"

Synergie Mistral:
Assisted average speed - 12 mph (using minimum effort)

After reading on A to B's website, I personally think the Powabyke should be on "The Maestro's" short list if he wants a cheap e-bike bought locally, in case it goes wrong, just for commuting to work.

Well I went to look at a few today and tried a 24 Speed Communter Powabyke at Redline Garage in Garstang and a Giant Twist at Apple bikes in Lytham St. Annes. I didn't think they were much good for me to be perfectly honest, I seemed to actually find that cycling in the 0-15 mph range was worse than on a normal bike and it was noticably harder to pedal. The motors seemed to cut out at a very low speed. I thought that 15mph was a lot faster!

I think its going to have to be a normal bike for me or something that is legally dubious.

Agreed. 15mph is likewise too slow for me, so legally dubious it may have to be. If you can try a Torq 1 do so and then on your days with cold, hangover etc, you can just twist and go at a speed at least approaching your unassisted bike, which you may prefer to use when feeling up to it.

I am reasonably fit and reasonably young and find that the Torq just takes away the irritation of having to pedal when I can't be bothered. For a commute of your distance and someone of your fitness, it strikes me as ideal.

Although street legal electric bikes are not as fast as most people would like them to be they are a great help especially in hilly areas and especially to older or unfit people. Regular cycling was always hard work to me.. even when I went touring in my youth and would ride up to 100 miles in a day and I still only averaged around 12 mph. The point is.. electric bikes make riding EASY and more of a pleasure

Yes I can see that even with the restrictions they are a very valuable form of transport for a large minority of people. My initial impressions of legal bikes as a young reasonably fit rider haven't been good its true but I've only done a few hundred meters on the bikes outside the cycle shops. Obviously I wasn't tired at the time and could easily have whipped up to 30 on a normal bike. I might have really felt the benefit after a few miles of cycling, its just so hard to tell.

I don't know the reasons for the 15 mph speed limit, maybe there are good ones. To me it would make more sense to allow motor assistance up to normal cycling speeds for young fit riders, say 25-30mph. That way the bikes really would go mass market and make a difference in tackling congestion and pollution etc. There would obviously be more accidents but the benefits massively outweigh the inevitable problems.

I didn't think you'd be impressed!

In my opinion, electric bikes are a great product and open up cycling to many people who would not otherwise do it, or would not do it anything like as much. But they aren't really designed for a young, fit, competent cyclist in a flat area who wants to go fast.

If you want to take it easy and go at a significantly lower speed than you normally ride, then you will find plenty of bikes that suit you - but if you want to go your normal speeds, you will either need to spend a significant amount of time fine-tuning a (non-legal) kit, or stick to pedal power!

Maestro,

Whilst we have no reports of the latest Wisper, I can thoroughly recommend its predecessor, the 905E. I've had one for about 3 months, done 1300 miles (17miles each way to work on most days). I have 'fortunately' suffered a malfunction whereby one of the wires to the speed restriction circuitry has 'fallen off' - I can achieve 20 + mph on the flat (headwind permitting) with a bit of pedalling and I'm not exactly in the fittest cyclist on the forum. I can complete the 17 mile journey in 1 hour with maximum throttle assistance for about 1/3 of the journey (pedelec assistance for the rest).
As the initial specs for the 905SE included a 'derestriction mode', the battery is supposed to have about 40% more capacity and the bike itself is supposed to be mechanically superior to its predecessor, assuming the motor/controller combination will not constitute a retrograde step, the capabilities of the 905SE should exceed those of the 905E. This should go a long way to meeting your requirements for a 10 mile each way trip - the only problem would appear to be the price but then every 'silver lining' has a cloud .
Also, when you come off the throttle, pedalling at 15 - 20 MPH is definately harder than on a conventional bike (well those at the top end anyway) and you can feel a resistance but, IMHO this is made up for by the assistance at the lower end of the scale.
I should add that (apart from advice on how to effect such a 'convenient' malfunction) the guys at Wisper have been quite helpful to myself and others on the forum so that should go some way to adressing your concerns about after sales support. Admittedly they are some 2-300 miles away but I've had no problems that would require anything to be returned to them - the only thing being basic cycle maintenance (brake pads) which they say they have addressed on the 905SE.

Regards,
