    So will it take you up Hardknott Pass at 15mph?

    Given my experience this afternoon, i'd say that a powerful ebike (such as this) would probably take you up a lakeland pass at 15mph in turbo mode... it would probably drain about 20% of the battery, although free-wheeling down the other side would balance that out a little.

    I'll be cycling over the Kirkstone Pass to the Loughrigg Fell Race in a few weeks time, so i'll let you know!

    I know very little about e-bikes but do they have regenerative braking?

    Whilst walking in the Italian alps a couple of years ago we were surprised at the number of e-bikes up at the high mountain huts and fighting for the very limited number of outlets available for re-charging their batteries.
    Cause tramps like us, baby we were born to run

    According to my power calculator, which came via a cycling forum where it was considered to be reasonably accurate, for a 78kg rider on a 33% incline (Hardknott), if you only soft-pedal and so rely entirely on the electric assistance, then with the most powerful motor currently supplied, (250w), the top speed comes out at 1.9mph.

    At this speed balance becomes an issue, so I think you'll need more than the token effort required to activate the motor (it only assists when you turn the pedals - for those who weren't aware of this).

    On initial impressions, very pleased with it. The motors are restricted to around 15mph in the UK, and on the bike this seems quite a low speed to cut out.

    Given the power of the motor, i could have perhaps managed with a lesser motor and gone for one of the Bianchi road e-bikes... but given the extras such as integral lights, guards, rack, plus being at least 1000 cheaper than the Bianchi bikes, it would look like i made the correct choice.

    My understanding of the legislation is that all e-bikes have their electrical assistance terminated at 15.5 mph, on the basis that a higher value would make them a motorbike, and subject to compulsory helmet, insurance etc.

    Of course this doesn't mean you can't exceed 15.5 mph, it just means that you'll have to pedal or roll downhill to achieve a higher speed. Talking to the portly rider of the Bianchi Aria e-bike I met a few weeks ago he explained that cycling with an e-bike involved using a different strategy. He chose to deliberately keep the speed below 15.5 mph on the slight inclines that pass as hills around here, so that he got full electrical assistance. On the flat and the slight downhills he could, and did, look after himself

    I can see where I am headed, slowly.

    I think that the legislators have made a pigs ear of the legislation in relation to e-bikes and e-scooters both of which are limited to a speed of 15.5 mph.

    A minimum of a provisional licence is needed for a scooter, which can only currently be ridden in a public place if hired, but nothing required for an e-bike.

    Another area where the lawyers will be laughing all the way to the bank in the next few years.

    My son has just bought himself an e-scooter, and he was told that the Police take a sensible attitude, i.e. they will only stop you on an e-scooter if you are actually causing a nuisance; they recognise that the current legislation is daft.

    Well, I'll report back in 3 weeks after the practical test on Kirkstone!
