    In an attempt to assist the OP and others who asked about the Orbea.

    The assistance offered by the compact motor is relatively modest, and in any case it couldn't deliver a lot of power for long due to the small capacity battery.

    This set up may well suit a rider who is coming at ebikes from already being a reasonably fit cyclist.

    It wouldn't suit Mr Sedentary Late Middle Aged Spread who hasn't ridden a bicycle in decades.

    Slightly against the Orbea is the general point that the control of hub motors is less sophisticated than that of crank drives.

    A quality crank drive - usually Bosch or Yamaha - has speed, cadence and torque sensors which makes it feel more like a bicycle to ride, something which may be appreciated by an experienced cyclist and lost on an inexperienced one.

    I would urge anyone thinking of the Orbea to also try something like the Giant Road E, which has the Yamaha crank drive motor.

    The difference in terms of poke and feel of the ride will be signifcant.

    Crank drives also offer no resistance when switched off/the bike is freewheeling, but some hub motors do drag.

    The first thing I would do on inspecting an Orbea is lift the back wheel and spin it - it may spin like an ordinary bike wheel, which is fine, but it may not.

    I see Tredz has a 2016 Road E for about the same price as the Orbea.

    The Giant is the more capable ebike in every respect.

    But as observed, that's not much good if you can't live with the looks.

    Do you have any advice about battery companies/types pale rider?

    I get the impression that this is one of the key factors if you want to stick with a bike long term.

    Personally I think quality suppliers of these contraptions should guarantee continued power bits supply until you pop it or give your heirs a substantial refund/cashback. A not unreasonable expectation I think.

    If the bike/battery is by a reputable maker, you would first rely on them for spares.

    Bosch, for example, guarantee to supply apares for seven or eight years after the product drops from the current range.

    All ebike batteries are made from rechargeable cells, similar in size to an AAA cell, wired in series and in parallel to give the required voltage.

    If a pack fails, replacement cells are readily available even if they might not be the exact spec of the originals - usually better spec as battery technology inches forward.

    There are also re-celling companies who will do the job.

    Similar applies to motors and controllers - widely available.

    Where you might fall out of bed with the Orbea is the tiny amount of Orbea-only components, whch effectively amounts to the button on the top tube.

    Even if replacements cease to be available, no doubt you could wire it using an ordinary switch.

    So an ebike is like an ordinary bike - there is nearly always a way of keeping one going.

    But as with ordinary bikes, some repairs may be more than the bike's worth.

    A cheap Chinese ebike with a burned out motor and a knackered battery wouldn't be worth spending the several hundreds it would cost to get it going.

    Yes had the idea that bosch was a good idea.

    The route i would very probably go if eventually going electric.

    I don't believe all the hyped-up "green" nonsense about electric & hybrid cars for exactly the same reason. When looking at whether something is really "green" you have to consider how much resources went into making it, and divide that by how many years service you manage to get out of it. One of my motors is almost 59 years old, and still has all of it's original mechanical units, so I won't be taking any lectures from pious tree-huggers about how "green" their new car full of toxic batteries is, until such time as it outlasts mine. Most modern non-electric push bikes are not going to survive anywhere near as long as old school ones have either. It's a throwaway world today and there's nothing "green" about it!

    I have no time for the e-bike detractors who've never tried one, try one first, then spill out your experience here.

    The way I see it, if you ride at (say) 200 watts on a regular bike and on an e-bike, you're getting the same amount of exercise by and large.
    E-bikes are great fun, my only concerns right now are the lack of standards, so if in perhaps 5 years you need a new battery for your Trek/Specialised or whatever, will they still make/supply them?

    Yep, greeness can be middle c!ass bull shoot. Suppose bullshit is green.

    I know a family (italian as it happens) who pride themselves on being green, wiv a solar panel. 3 folk in the house, 3 cars, mostly do round trips of 10 to 15 miles.

    Bosch currently dominate the premium end of the market, dozens of makers offer Bosch powered bikes.

    I believe production of the motor has passed two million - a massive number for a bicycle component.

    I've heard of a handful of breakdowns, but in the context of numbers sold Bosch is one of the more reliable ebike motors.

    A surprising number of companies make crank drives for ebikes, Yamaha, Brose, Shimano, Continental (as in tyres), Bafang, Panasonic, Kalkhoff and lots of others most of which neither you nor I will have heard of.

    The majority of which sell in thousands or tens of thousands.

    Things change, but Bosch's stranglehold on the crank drive market looks likely to remain firm for a while yet.
