Matar9000 said:FlyingFinn, I saw you posted a picture of your bike on the top of a cold mountain. I'm in Canada where it gets pretty cold in the winter and would like to ride my bike all year round. How do you say it reacts to cold temperatures (breaks and suspensions)?
And, how cold was it, here it often gets to -20°C and sometimes -30°C, do you think the bike would still ride well at those temps?
Hi to the other side of the North Pole!
I’ve ridden the bike only as low as -18 C (this winter was a joke in Europe). On that exact trip with the photo you mentioned the rear brake (seals?) froze and spewed the brake fluids on my pants. Middle of Lapland so no bike shops anywhere. Improvised and filled the Magura MT5 rear brake with baby oil. Worked 100%. Rest of the week long trip with 150km’s of driving in various conditions ranging from +3 to -15 C without any issues.
Before that the bike was hauled 1000 kilometers behind a car in a rear-rack gathering ice and road salt. No issues whatsoever.
Front suspension becomes stiff and unresponsive in below -5 C. This is 100% normal for all forks except Wren. Rear suspension works really well after initial slugishness even when the bike is stored outside. Your pedaling action creates movement and thus friction creates heat in the rear shock.
It’s clear that you must bring the battery inside for storage or charging. If you would leave with a room temp battery and driving constantly the battery shouldn’t loose it’s capacity more than 10% no matter how cold it is. I bought this sleeve in order to maintain the heat in ultra long and stopover trips in the cold: https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F392197710810
The sleeve won’t warm up a cold battery nor provide any capacity boost if you just ride non-stop. When it’s at it’s best is a trip where you need to stop for eg. 30-60 minutes and leave the bike outside in the cold. In those conditions you could easily contain 30%-50% more of battery capacity with this.
The fat tire pressures are really nit-picky about temps. From inside +20 to outside -20 and it would be like transforming from motorcycle tires to driving on a used condom. You need to have a small hand pump with you anyway. Pressure adjust is a must.
The bike in XL size is veeery tall and long. 220 cm long and maybe top tube is 140 cm in height. Motor ground clearance is the double compared to other bikes. Any rear racks won’t accomodate these kind of monsters. I’ve used Thule Velospace XT 2 with XXL-size special wheel straps. Even with these measures the bike fits barely

Just hit me with any questions. I haven’t ridden in deep snow since Southern Finland doesn’t have any and in Lapland there’s over 1 meter of it. Sweetspot could be maybe 20-40 cm in which the bike would really help you move around.
