Columba 26 Inch Alloy Folding Bike w.18 Speed & Double Suspension

I bought this bike back in April 2012. It is now June 2013 and I have used it on and off for a total of maybe 700 miles or so, which I know isn't heavy use but what can I say. After a year of using this it still runs great. The tread is a little worn but it has a ways to go yet before replacing, appears barely worn. I love this bike considering it only cost $279 when I bought it. Assembly was fairly easy.Some important suggestions if you are buying this or any other variant of this model. When assembling or re-assembling the folding bike remember that it is really easy to have the front forks and wheel turned around. An easy rule to remember is (and Im going to use all caps to help you recall this is that THE FRONT BRAKE CALIPERS SHOULD ALWAYS BE *IN FRONT OF* THE FORKS. If you assemble the bike from a folding state (where you removed the handlebars) and notice that the front brake calipers are BEHIND the front forks then STOP and flip the wheel around. Riding the bike in this fashion is quite dangerous, in particular on inclines. I learned this the hard way when I assembled it while tired - front wheel was backwards and I went out for a quickie run and almost smacked into a curb because my stopping power was greatly diminished.So, remember - FRONT BRAKES FORWARD. You can even draw a small arrow pointing "this way forward" on the fork tubes using a Sharpie as an extra measure. We all do stupid things when we are tired!Another suggestion is to get a Gel-seat overlay which makes riding this thing super-comfy. Also, this bike has a max weight rating of 200 lbs so if you are like me and hovering around the 2 bill mark on the scale, consider stiffening the rear shock to compensate. I am no expert but it just seemed like the read shock was tuned for someone fairly light.I found that the tire inflation pressure of around 55PSI feels like the optimal tradeoff between road rumble and rolling resistance. The max pressure is 65 PSI. Here on Amazon there are a number of gel-seat overlays for around $20-40.Continuing suggestions, if you are going to buy this model then definitely get a large strap to secure the wheels together when you fold it up, otherwise the bike will flop around and be quite difficult to handle folded up. What I did: I found some SCORPION STRAPS and combined two of them to create one large velcro strap which is perfect for securing the wheels together. I think you can find these scorpion velcro straps here on Amazon somewhere.Final suggestion - I would strongly suggest buying a Park Tool 3-way wrench also here on Amazon. T10 T25 and T30 wrench sizes. The reason is that you will almost certainly need to play around with the brake pads and to get them seated just right you are going to need an easy to handle Torx wrench. The one that comes with the bike is a simple key wrench which makes brake adjusting a lot harder than it has to be.So that's it! If you are much heavier than 210 pounds and/or over 6 feet tall then this bike is probably not going to be sturdy enough for you. Overall this bike is incredible, and it's no wonder that 2KSilver can't keep them in stock for long.

We got two of those bikes (red and silver) after reading all the positive reviews. Buying experience from 2KSIVER was good though there was several days delay - looked like they were out of stock (though the web site listed them in stock with 5 left). But they answered all emails promptly and did their best to get bikes delivered in time for our vacation.The bikes came securely packed and almost fully assembled, the red one had a small frame damage but that was not critical. No tools needed - unfold the frame and pedals, turn the seat, install the handlebar, inflate tires and you are ready to go. They do the trick - both easily fit in the back of our Subaru Outback with rear seatbacks down and that was what we needed the folding bikes for. First impression was good, bikes seem well build and ride is relatively comfortable thanks to double suspension. Few negative comments after the first ride:- Rear derailer in one bike needed adjustment, had to un-tight the cable screw and readjust cable length otherwise the gear number on the hand bar did not correspond with the number of the sprocket.- In both bikes real derailer guards were bent and prevented switching to gears 5 and 6. Had to manually straighten them. That and the previous problem with derailer would be impossible task for a lot of people with no mechanical skills - means visit to a repair shop.- Front derailer does not have gear number indication.- Despite of the alloy frame and rims they are relatively heavy - 34 lb.- They do not support riders heavier than 200 lb - come on, who they are for, just teens and girls?? should be good for 250 lb at least.- Both I and my wife found the narrow seats very uncomfortable. Ended up with spending $60 more for two wide soft seats (and Columba does make the wider seats part # 20A for the same price as the original part # 26A ones!). Besides, being 6'2" I had to order a longer 12" seat post separately. It should be possible to select seat post length and seat style while ordering the bikes!Other than that - nice bikes for the money, overall quality and durability seem to be good.

Very easy to assemble and really comfortable to ride. Folding bike up is a breeze but would recommend buying some type of bungee strap to tie front wheels together after folding. I had a gearing issue at first but was quickly resolved. Would recommend ordering longer seat post if you are 5’10 or taller. The front and middle shock mechanisms work great and create a super comfortable ride. Great company to do business with.

The media could not be loaded.  Great folding bicycle, Nice look, Soft and Confortable to ride, good Velocity, nice Twist Grip Gear, Pedals can be fold. Works as a 24 or 26 inches bike. Good quality, except that the break can be better, but not bad.I bought one for me (5 feet). After trying my daughter (5.5 feet) wants one for her, and my son (4.4) wants to change his bike for this one too. I contact the company and they help me right away, they send me a black bicycle with an extra seat post shorter ($14) for my son or you can cut the post by yourself.I bought 3 different brands before (Macee, Hahoo, Huuh) they were really bad.I had them for one month and we love it. Tried all terrains and it works amazing. I really recommend Columba Alloy bike.

We really like these bikes. We have a 4 door jeep and these fit nicely in the back (2) the seats are absolutely horrible I highly suggest ordering a new seat with the bike because we took them on a trip but the seats were so bad we were only able to ride for 40 min and had to park them the rest of the 2 days. I was really disappointed but luckily we brought our Jetson bikes too.

I have been carless most of this year and having this fold-up bike has saved me a lot of time and headaches. I bike everywhere with it. And I love that it can fold up and fit in almost any car trunk.
