  • All Terrain bikes are great for Alaska
Color: Silver/Black
Mongoose is the cheapest bike brand I could find and it certainly weathered well for the year I've been using it. It has great traction in snow, ice, and sand but mostly bought the fat tire bike to support my hefty weight. It took some getting used to at first but eventually got the ease of turning corners quickly. ... show more

I'm on the wrong side 50, a tad under 6 foot, and 310 lbs. Knee, shoulder, and foot issues prevent me from walking, lifting, or even working a heavy bag. So I bough the Mongoose Malus as a way to exercise. What others say is true - it's a basic bike that you'll have to replace parts on. The good news is that the replacements are easy and far cheaper than stepping up to a more expensive bikes. True, it is heavy, but if you're just trying to make it around the neighborhood for a couple of laps a day for the purpose of exercise, then that's actually a good thing. Parts you HAVE to replace: Seat - I went with the Sunlite Cloud-9 Bicycle Suspension Cruiser Saddle, Cruiser Gel, Tri-color Black Brakes - I used shimano brakes and the difference is night and day - I believe its because the stock brakes are so bad. They do not stop you quickly at all. They don't lock up the rotor. Shimano M375s Shifter - Like many, I thought - no big deal, I'll just avoid hitting it. I have larger than normal hands and the shifter takes up half the handlebar - so I upgraded to a shimano SL-M315-8R. Amazing upgrade. Pedals - there wasn't anything horribly wrong with the stock ones, but they were polymer and while the bike is rated for 350, I just didn't trust them to support my full weight if I get up on the pedals. Replaced with PD-EF205 I replaced some other stuff, but I wouldn't say it's required. The seat and shifter are ease of use issues, the brakes and pedals were potential safety problems. The replacement of all parts are easy. If you can assemble furniture, you can replace bike parts. It's 3 metric allens, a driver, a screw driver, and you will need some snips or something that can cut through wire - you have to cut through the wire on the stock brake and shifter assemblies to remove them - and that's fine. A pair of side cutters will work well. If you're fat and looking for a dependable cruiser you can't break - that's what I bought it for and so far this month I've got close to 95k on it, no issues. ... show more
