Electric motor and lithium-ion battery power the front wheel
29 April 2010

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'm sorry, but it looks f.stupid, and putting power to the front wheel of a bike is an even worse idea than doing the same with a car. Also, it'll be heavier than most bikes, thanks to the battery, and, because of the stupidly high saddle position and stupidly low handles, you'll have to pay regular visits to an osteopath... Lexus, stick to designing cars... oh, wait, you're no good at that either. Any chance you could bugger off and, instead of making your cars silent and perfectly-built but soulless, make them have character and make interesting noises instead? And, particularly, ABANDON THE HERESY THAT IS THE V6.

Must say I agree with some of the above perhaps in a more tactful way and am glad this will not reach production probably because there is no market for it and you would need to be a contortionist to ride it.

I have winced every time a car manufacturer has had a go at building bikes several have tried but this does seem to be the worst yet . On F1 team recently produced one as well and were trying to flog it for 20k yes that is a pushbike for 20k . Nuts.

Silly idea, stay away from markets you don't know or understand

The riding position is important on any bike, its set like that for "effect", the effect being putting people off.

Bicycles are powered by the rider, lets keep it that way

There is a booming market for electric bicycles in Israel, I can definitely see something like this work in the right price.

Erm... Electric pedal bikes have been around for years! They are all over the far east where they are really popular! And Lexus is from the far east so hardly new to them!

"The bike also uses an eight-speed Shimano internal gear system, which references the eight-speed shift-by-wire system found in the LS600h."

jeez. Talk about making a spurious connection! my Mazda 5 has 4 wheels which references the 4 wheels of the LeMans winning Mazda 787B.....

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

Well whoop-de-doo. That makes it really relevant, and such an important news story, Autocar...

As above, putting electric drive through the front wheel and tiny contact patch of front tyre is just asking for trouble. Wet greasy road or gravel on a corner, anyone?

Ok we haven't just stumbled upon some freak link to Cycling magazine and this news hit Auto express' RSS 2 days ago.

This bike is a design piece however; the seat and handle bars are fine for a normal road bike. It's purpose would be for commuting and my guess would be that an average rider would still be able to average 30mph over a 15-20min journey without breaking into sweat. The demographic buying Lexus have the money to spend £2000 on a carbon-fibre push bike this just saves them having to take a shower once they get to work.

This actually makes more sense that trying to stick the same size battery in a car and call it a hybrid, yet all manufacturers are hell bent on putting slabs of lithium-ion in a car and brain washing everyone into thinking it's ecologically responsible.

This bike and others like it would easy congestion in heavily built up areas, be less polluting, have a fantastic weight-power ratio and when to battery has reached it's end of life, it can be easily replaced. Unlike a car which far outweighs the power of an electric motor and lets not dwell on how stupid the thought is of lugging a dead, non-rechargeable, non-replaceable battery around.

Not unless you're married to an osteopath they bloody well aren't.

As for fantastic power/weight, if it had much power (going to the WRONG WHEEL), it'd crash. And, remember, there are no side impact bars on a bike, and minimal crumple zones... it's a bloody stupid idea. If you want a bike, get a bike. If you need a shower when you arrive at your destination, man up and get fit. Hell, I'm pretty unfit and I still don't need a shower, even after a decent bike ride. 2k would buy me all sorts of lovely old luxobangers, even including running costs, so let's stop thinking that this idiotic thing has a future. It hasn't.

[/quote] 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...
