Competition: How far would you have to ride to generate enough energy to power an electric oven?


Uniqlo have launched their “convert your energy” campaign. Using kinetic energy pads, customers can generate power through movement. The promotion is related to the new HEATTECH gear that is now being sold in stores and online. Needless to say, the promotion is perfectly timed for the coming winter chills! (And will be particularly good for people like me who always seem to feel the cold and spend most the day asking others: Do you feel cold?).

As part of the promotion here on London Cyclist, Uniqlo have calculated how many kilometres someone would have to cycle to generate enough energy to power an electric oven for an hour.

To enter you need to answer the below question in the comments:

Q: How many km’s would you have to ride to generate enough energy to
power an electric oven for an hour?
a) 15km
b) 25km
c) 35km

The winner will have £100 to spend on any HEATTECH gear they want, from the Uniqlo store (there are both men’s HEATTECH and women’s HEATTECH choices). As we’re on the way to Christmas, this would be a good time to grab some of these tops as gifts.

Out of the correct answers, we’ll pick one winner at random using a random number generator.

Promotions will also be taking place in selected Uniqlo stores starting from October 25th until November 4th. This will be done using an innovative floor surface that will convert footsteps in to energy.

There will also be “Heat Spots” popping up around London in Garden, Soho Square, Westfield London, Westfield Stratford, and Bluewater where people can convert their social energy, to redeem a piece of HEATTECH.

The total converted energy from the promotion will be showcased on the in store screens.

HEATTECH is a new innovative brand of thermal clothing that is designed to lock in heat and keep you warm throughout the day. It’s also designed to be incredibly comfortable to wear to offer a soft and second skin like feeling to the wearer.

The heat spots will be at the London locations on the following days:
Covent Garden – Thursday 25 October –Sunday 28 October
Soho Square – Thursday 25 October –Sunday 28 October
Westfield London – Thursday 25 October –Sunday 28 October
Westfield Stratford – Monday 29 October –Saturday 4 November
Bluewater – Monday 29 October –Saturday 4 November

Our usual competition rules apply. The winner will be announced on this post.

Please note this is a paid promotion by Uniqlo.

    C – even further if its a fan oven or a high temperature . Not sure about Halogen ones though.

    Probably C but could be B – no mention of what is being cooked which may have some bearing and how fast you have to pedal – in my case probably about twice the distance as I am quite a steady pedaller

  14. John 22/10/2012 at 9:22 pm #

    answer B

  16. TrekTrev 23/10/2012 at 8:11 am #

    I’m going with – C!

    I read somewhere that the average cyclist puts out about 100W; so at 15km/h my back of a fag packet calculation makes it about 150km to generate 1kW/h.

    I guess the oven wouldn’t be on 1kW the whole time, but even so your answer must be C.

    But God forbid I ever wear thermals.. got a built-in thermal vest made of pies!

      Aah, the pie related mystery of the ages finally solved.

  19. Alex 23/10/2012 at 10:56 am #


    About to head into my first London winter commuting on the bike so a set of thermals would be excellent!

  22. SarahS 23/10/2012 at 12:01 pm #

    C I should think.

    Stab in the dark…C

  27. Matt 23/10/2012 at 12:09 pm #

    It’s C

  28. Matt Delaney 23/10/2012 at 12:17 pm #

    Answer is C

  29. stefania 23/10/2012 at 12:20 pm #

    A (15km)

  30. Chico Urbanus 23/10/2012 at 12:21 pm #


  31. Tory 23/10/2012 at 12:21 pm #

    Everyone’s saying C…and I agree!

  32. Dean 23/10/2012 at 12:21 pm #


  33. Cameron 23/10/2012 at 12:31 pm #

    C is my guess! 😀

  38. Diana 23/10/2012 at 1:37 pm #

    Let’s go with C.

  39. Yoshi Hayashi 23/10/2012 at 1:53 pm #

    To be honest it depends on how much power you’re putting in to the pedals and the wattage of the oven not to mention a whole barrage of other variables, but since everyone is saying ‘C’ let’s go with C!

  40. Gareth 23/10/2012 at 2:04 pm #

    C, I reckon.

  43. e 23/10/2012 at 2:33 pm #

    a,15km, just to be different… 🙂

  44. gordon 23/10/2012 at 2:51 pm #

    There is no way to accurately answer this question as it would vary greatly from person to person, the average cyclist (I’m told) would put out a steady 250 watt/ph, I know that at a steady pace I usually put out 450/480 watt/ph and a professional cyclist puts out 1200/1600 watt/ph during the last hour of a race, so A is the answer I’m going to choose.

  45. Carolyn 23/10/2012 at 2:51 pm #

    How big is the oven and what are you cooking? 🙂
