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.

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.

Simply put, this is a fantastic fat tire bike for the incredible price of less than $250. I've already put in over 60 miles in the last couple of weeks, and it's just a joy to ride. I was pleasantly surprised at the power/torque this bike has when tackling hills. I was a bit worried about how it would handle steep inclines given its weight, but man... the first steep elevated trail bridge I climbed, I easily outpaced others who were riding multi-geared road bikes. This puppy can also easily take off from a standstill with little effort. I was originally looking for a bike with a smooth ride for suburban/trail biking, and this has proven to be exactly what I wanted. This is by far the least expensive bike I've ever purchased, but it's also the MOST FUN I've ever ridden! I'm sure the $2,000 - $6,000 fat tire bikes would smoke this in a heartbeat, but seriously... for under $250, this thing over-delivers! Rides really well on paved and gravel paths. Plus, it's always a hoot to hear the various comments from others who've never seen a fat tire bike before! Is it perfect? No. The one thing I would recommend that everyone upgrades immediately is the seat. I know that bike seat comfort is highly personal and subjective, but I found the factory seat to just be rock hard and uncomfortable for any ride over a few miles. So for another small investment of $45 for a quality seat, I'm sitting comfortably at 20+ mile rides with no complaints. Pros: - Low cost but solid quality - FUN to ride. There's nothing like fat tire biking. - Nice power/torque. Easy hill climbing and quick take offs. - Fairly easy to assemble. Cons: - Factory seat is a bit hard. Recommend replacing ASAP. - Mine was missing a nut for the front tire assembly... minor inconvenience though. Summary: - Looking for an intro to fat tire biking? BUY THIS. You won't regret it.
