This is us ! Who are we ?

Marianne Bellerose


I’m the creator of the company and I’m the one who makes all the ByCKL clothes right now. I graduated from Lasalle College in 2006 with a male specialization. My intention as soon as I entered college was to have my own clothing business. I tried the first time in 2007 which did not bear fruit. When I ended it I thought I should have a specific product with a target clientele for a future project because making clothes to make them with my particular style made my customer search more difficult despite my concept of customization. I left the project on ice waiting for the right moment.

The bike began to take up more space in my life as a means of transportation in 2009 as I start working on Cirque du Soleil touring shows where I started to clothing / costume under another eye. I was never a fan of lycra kits and at that time it was not as stylized as what is on the market right now. The day I wore one of my jeans to work was the worst time of my life I suffered martyrdom with the crotch seams. The designer in me woke up again and my research began. I went to San Francisco to visit established brands and again there were very few options for women. I came back to Quebec and jumped on the drawing board to make my personal wardrobe and rekindle the entrepreneurial flame.

I started developing clothing under MB Design Bike Wear in 2010, I added men’s clothing in 2012 in collaboration with Sébastien Mignot for tests and advices, I changed my name in 2017 for ByCKL by MB Design where I make the clothes of the brand ByCKL, I also make circus costumes and stage accessories that allows me to live the super power that life has given me.

What makes me vibrate the most through the products I make is to give them a meaning and a utility, to use my brain to create a product that will help to the person who will use it by taking into consideration the needs. I like to say that there’s never a problem only solutions, just take the time to think and try something.

Thank you for being part of my adventure and doing business with me, you have no idea how happy it makes me, says the girl who dances alone when she has orders!

Claude Boies

A biography!? I never know if I should start with beginning (the moment my mother welcomes me to the earth and finally give hope to humanity) or if I must focus on my ultimate achievements on this earth. Who am I? Oh, the existential question! Humor is a constant part of my life, not laughing in a day is absolutely impossible and unacceptable. Big fan of everyday life, I found myself in diversity. In my professional life I’m a manager for a telecommunication company (yes, a boss, watch out!), but no worries I’m taking good care of my people… Well I think 😉. I am also the father of a wonderful teenager, whose only goal in life to test my patience (I’m sure you understand that’s the primary role of a young teenager, so I cannot blame him. Well not always!). 

You'll probably ask yourself the following question "Where you came from with your skis to work with ByCKL?" First, I really hope that you didn’t ask yourself this question and secondly the adventure began quietly after meeting Marianne and understood how this company is her child love and her passion. Over time she knew, quite easily, to share hey passion for urban clothing and cycling by the same, but we get along immediately, what she does (clothes, cap, scarf and way more) is just perfect !!

So, to resume I work in partnership with Marianne on the communication, marketing, blog, administrative, transportation and above all other related tasks links to the company. Basically, I'm always busy, but the experience I’m getting from pay me an hundred time and working to give you all the best of what ByCKL can offer, fully worth its weight of gold!

Oh, before I forget, I never exaggerate the facts! I don’t think so! I’m pretty sure! Well! 😉
