Lexus has launched its innovative Hybrid Bicycle Concept in the UK.

The bike, first seen at last year's Tokyo motor show, is being used to promote the firm's sponsorship of the four-day Great British Bike Ride charity event from Land's End to Twickenham.

The firm's 'L-finesse' design language has inspired the design of the frame, which is made from carbonfibre. The rider powers the rear wheel, while the 240w electric motor and 25.9V lithium-ion battery power the front wheel.

The electric motor can be switched between Eco and Power modes; an energy recuperation system helps recover energy lost under braking. The bike also uses an eight-speed Shimano internal gear system, which references the eight-speed shift-by-wire system found in the LS600h.

Just two of the concept bicycles have been made - there are currently no plans to put it into production.

I've ridden plenty of bikes, thanks, and driven plenty of cars. I'm well enough informed to tell you that you need to be married to an osteopath to ride a bike with a seating position like this. It's got nothing to do with efficiency or power from the legs. It just looks stupid, crushes your stomach and makes your back ache like hell. I have never pretended to be an expert on a car where I have no experience of it - sometimes I've condemned a car for its looks, or because someone I know well has found it to be unsatisfactory, but I have never claimed expertise where I haven't driven the car in question.

This is a road bike, the position is common for a road bike. It isn't a mountain bike or what is known in the cycling industry as a 'Hybrid' These have an upright seating position as opposed to road bikes. Driving the front wheel won't make it crash but too much power will cause loss of traction and personally I'd rather the power be moved to the back wheel. As for not needing a shower after a decent bike ride leaves the question on what is considered a 'decent bike ride'. To average 30mph on a normal bike will without doubt will cause the rider to perspire. It's actually easier to point out that any physical-exertion for an extended period of time will cause you to sweat. Various factors change at what point you start to sweat and how much, i.e atmospheric temperature, what you are wearing, whether you are tired, ill or under any form of medication. 2 grand will buy you a small used car and using one will have defeated to object of this form of transport. which is Light-weight compact and less harmful to the environment.

Unfortunately I must now explain light-weight. The average carbon-fibre bike weighs in at around 7Kg (UCI regulates a minimum is 6.8Kg for pro-competition) thus manufacturers don't often go below 7Kg, however some bikes are produced with a weight of just 5.5kg including running gear not just the frame but they sell for around £6,000. From this it's easy to see that a small battery pack added to any Carbon-fibre bike will still keep it under 10Kg.

There are already many electric bikes in production which means this type of bike does have a future. With many people already willing to spend 1-2000 pounds on a bicycle then it's feasible to think that they would spend the same on something like this.

Well, I can tell you, my road bike has a much more upright seating position - but then, it is slightly older than I am. I look at the majority of modern bikes and just think 'no, that's awful'. Stick to thin-tubed touring bikes with bull-horn handlebars, they're still the best. I tried a bike with a seating position like this one and my back ached for days afterwards, and others I've spoken to have said the same. Anyway, I'm still of the opinion that I'd rather spend 2k on an old luxobarge, like an E34 5-series or even an old E39...
