Brakes
180mm discs, Avid mechanical.

Extras
Last changes is black Enabler fork, aluminium diamond plate cover and fixed rear light.

Summary
 It is fun and capable electric cargo bike to replace car in most tasks. It works well even in -20c winter degrees.

400/1 and food

"Making bikes that outcompete other bikes is not relevant. Making bikes that outcompete cars... that's interesting"- Jens Martin Skibsted

Winter cycling is bliss with right gear. I have ridden over fifteen winters but two last with electric Mukluk and it has been paradise for bike freak. Conservative cyclists may not give any respect for electric motor in bicycle but I take it as an experiment. Machines that are capable to do the every day jobs: transporting you 15 km in late hours after dinner in heavy snowstorm, transporting groceries and kids, making your commuting to work possible in coldest and challenging road conditions days.

I used to ride fixed Monark 92320 conversion with 35mm tires in winter. It sure was more sporty, sweaty and slow way to move, but in some winter days the bliss was bit too far. Don't mind being wet from exercise but the biggest difference to eMukluk riding  is that I don't think the snowy weather, road conditions, distances and the way I dress anymore. I just ride and that's good for my zenish mind. Car, train or bus is less and less attractive idea in winter.

I spend 1 euro for every 400 kilometers to charge the battery in eMukluk, I spend more money in food even if I use car or aeroplane in same distance.

Reynolds 531 decal marks can be seen on fork.

Quality of Movement

No one loves to be in traffic jam in car, it's really waste of time and money. You cannot do anything else than just check the brake lights in front of you. You take too much space in city and polute air by burning oil, instead burning fat.  Is it really necessary to take the space of your kitchen or bath room with your car in city road or parking spots when you traveling alone?

Crystal clear it is, quality in movement is my passion. In past few days I  have realized that everything in movement has come to some kind of strange wisdom point. Life and time itself is movement. Winter swimming in frozen sea combined with hot smoked sauna and fat biking underlined this yesterday.

Efficiency in bicycling, in time measuring, in art and quality of transportation in every day life it is. I admire the micro mechanical world of watches, the quality of bicycle in traveling and potential of performance art in story telling. All done with brilliant ideas and great skills. Quality in movement.

Creative and Fat Times

Winter can been seen as off-season for bicycle things. This is not completely true, people are defining (or specsing) new complete bicycles, frames and parts for their new ideas of their cyclist career. Some propel heads and folio helmets has totally new approaches to problems in question.

In tandem, primary chain tension might be problem if you do not have eccentric bottom bracket. This solution was done with two extra chain wheels floating freely between lower and upper chain. This fixed gear tandem was build in Pyöräpaja and it was seen in Yksivaihde.net x-mas party.

Helsinki city is taking good care of the normal roads in winter but roads for bicicles are in so bad shape,  so I started to ride fat bike in last winter. Second winter, with hub motor in front, 30km daily commuting ride is pure bliss for the lazy bastard. Cargo sledge pulled to the same party by eMulkul.
