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.

    Agree that the questionis not specific enough, as others say it depends on pedal power…so I go in the middle

  2. Alistair 24/10/2012 at 2:20 pm #


    My working is that the average oven energy consumption is 1.5kWh, a human can produce an average of 45W when cycling.

    kWh to kW = 1.5k x 1 = 1500 W

    1500 W / 44 W = 34.1

    • Alan Moore 24/10/2012 at 2:48 pm #

      That’s 34.1… hours. Hundreds of kilometers!

      I was not very far away from that either, though. The basic point though is that an oven takes LOADS of power and a bicycle doesn’t.

  4. Ade Bradley 24/10/2012 at 8:00 pm #

    I’m gonna go for C

  5. Esteban 25/10/2012 at 10:02 am #

    c) 35km

  6. Rodrigo 25/10/2012 at 5:10 pm #

    Answer C

  7. Sarah 25/10/2012 at 6:05 pm #

    C! Depending on the oven temperature and based on my own cycling abilities 🙂

  8. Caroline Maynard 26/10/2012 at 12:41 am #

    C. Me too.

  9. Mark 26/10/2012 at 10:07 am #

    A very unscientific C

  10. Flavia 26/10/2012 at 10:12 am #

    35 km!

  11. David 26/10/2012 at 10:13 am #

    I’ll plump for C

  12. Paul 26/10/2012 at 10:14 am #

    Yes, C is my concrete guess. Dont know whether it would get an AGA up and running though!

  13. Jules 26/10/2012 at 10:16 am #

    a) 15km

  14. Amandee 26/10/2012 at 10:16 am #


  15. Tom 26/10/2012 at 10:17 am #

    I’ll put my electric oven on a low heat to keep the plates warm and go for A.

  19. coney 26/10/2012 at 10:24 am #

    there’s SO many variables to consider when answering this question…….I won’t even get started. but I’ll choose A.

  20. Wesley 26/10/2012 at 10:31 am #


  21. Andy ZE2 26/10/2012 at 10:34 am #

    A for me please. With snow on the ground today I could really do with this stuff. Shetland is a place where winter is 9 months followed by summer, 3 months of cold and windy weather!

  22. Chris Mathieson 26/10/2012 at 10:41 am #

    I’ll go for A) 15kw

  23. Sam Williams 26/10/2012 at 10:48 am #

  26. Lizzie 26/10/2012 at 10:50 am #

    C) please Bob

  27. Christian 26/10/2012 at 10:57 am #

    A please.

  28. Chia Huei Tan 26/10/2012 at 11:02 am #

    Is the oven already pre-heated? Going by the way I heat up like mad within 1km of cycling, and maybe taking the pre-heating into account (and just power it for an hour!), then my answer is A!

  29. peter mccloskey 26/10/2012 at 11:06 am #

    must be c

  30. Mike 26/10/2012 at 11:12 am #

    It’s got to be C, unless you’re talking a very small, very cool oven. But hey, it’s only for fun, yeah?

    Definitely C.

  31. Justin 26/10/2012 at 11:27 am #

    B for Baking..!

  32. Jason 26/10/2012 at 11:53 am #

    C please! Wouldn’t want to have to cycle 35km every time I wanted to bake some cookies – although they would taste so much better after that cycle!

  33. Andrew Short 26/10/2012 at 11:54 am #


  34. Peter 26/10/2012 at 11:58 am #

    C in my opinion

  35. Carlos (Not2be) 26/10/2012 at 12:00 pm #

    I will go for answer A…

  36. Eddie 26/10/2012 at 12:50 pm #

    I’m gonna go for C…

  37. Dave Greenwood 26/10/2012 at 2:03 pm #

    I’m guessing c) 35km

  42. Hugh 26/10/2012 at 4:53 pm #

    How fast am I cycling? Into a headwind, or with a tailwind? Uphill or down?

    And are we cooking a meringue, a stew, or am I crackling pork? In a modern convection oven, or an old 1970s model?

    Assuming I am cycling on the flat, with no wind, at a fairly sedate 15mph, and that I will be cooking a stew in a modern oven, I am saying C

    • Chris C 28/10/2012 at 10:44 pm #


  43. Chris 26/10/2012 at 4:59 pm #

    I think C

    You could cycle 25km in an hour and I don’t think you would be generating enough enegy per minute to power an oven (but I may be wrong) therefore I assume you would need to be cycling for more than 1 hour – hence 35km

  44. Milind 26/10/2012 at 5:10 pm #


    • Oweneagle 26/10/2012 at 5:48 pm #

      I’d go for:
      B) 25km

  45. philcycle 26/10/2012 at 6:01 pm #


  46. Scott Wall 26/10/2012 at 7:08 pm #

    35km if you like your food well done!

  47. Steve 26/10/2012 at 8:11 pm #

    C – 35km

  48. Andy Moran 26/10/2012 at 8:40 pm #

    Must be (c). 35km

  49. Tom 26/10/2012 at 11:35 pm #


  50. Charlie 26/10/2012 at 11:44 pm #

    Got to be (C)
