Kingttu G6 Mountain Bike 26 Inches 3 Spoke Wheels Dual Suspension Folding Bike 21 Speed MTB Bicycle (G6 Mag Green)

Bike arrived sooner than expected which was great but box was ripped. Assembly was pretty easy, had it ready to ride in 45 minutes. Plastic pedals so not impressed with that. Brakes kinda noisy and did not stop as well as they should. Rear shock was kind of spongy. With all that, tool it out for a quick ride and 2 miles in decided definitely not the bike for me. Frame was too small even they said height recommendation was up to 5'9. I'm 5'8 and it's too small. Rode good, shifting is smooth but rear shock definitely could use some improvement. Decent for a teen but I don't think this bike is adult ready.

As advertised... love it!

I needed to find a bike to fit in my super compact car, and for a variety of reasons I couldn't get a Montague Paratrooper, which might be closer to my needs.I am not sure that I would trust the frame for actual MTB riding, but it works fine.I'll be honest, I was not impressed with the components (front/rear shock, rear shock bushings, crankset, arms, pedals, handlebars, seat, steat post, tires, stem, rear freewheel, brakes). So I upgraded nearly everything on this bike, and I wanted to write this review to go over the parts.Frame Measurement: 16 inchesFork: Metal Suspension ForkRear shock: 150mm (I can't remember now, but I don't remember it being adjustable)Rear shock bushings: Top: 54mm x 12mm (eyelet) x8mm (bolt).

The seat is a seat, it's not bad or good2. While you may be able to change the front axle out and go with quick release, the rear is probably difficult.3. The components, and sort of the bike as a whole, is really a kids bike, and it rides as such heavy and clunky.4. The rear shock is not adjustable, I think the front shock is adjustable but I never found it to change much.5. As a 3x7, freewheel configuration, there are very little drivetrain upgrades available, you may be able to squeeze an 8 speed rear cog on, but I have not tried.6. The bike doesn't really have a decent top end, so pedal fast if you want to go fast.7. I would be extremely worried about any medium-advanced mountain bike riding on this, I am not sure the frame will take the abuse. That's to be expected from an entry level MTB. Light trails and commuting are really what this bike should be used for.8. The top bushing on the rear shock was free spinning, and very hard to find a good replacement.All that being said, the bike looks cool, and I needed a covid project, so I upgraded pretty much everythingHere is what I gotHandlebars: Controltech Risk 15mm scandium handlebars (good cost vs weight)Shift levers: Shimano SL-M315R7 and SLM-315L (Rapid fire)Brake levers: Shimano BL-MT400 (hydraulic)Stem: Satori ET2 AHS (the stem can turn 90 degrees, which helps on a folding bike)Headset Bearings: sorry I left the press fits aloneFront Shock: Rockshox Recon 26" Silver TK Solo airTire: Continental Race King II (German made) 26"x2.20" (before you go with a 2.20" you might want to check that the rim can handle it, they seem fine, and aren't bulging weird, I decided to just go for it)Brakes: Alvio BR-M4000 (hydraulic Front and back)Brake Rotor: Avid G3 160mmSeatpost: 400mm aluminumSeat: BetterRear shock: KS Evo 562r (Air shock)Front derailleur: Shimano Altus FD-M310 (66-69 degree, bottom swing (due to spacing problems with the rear shock rails, the thicker clamp would not work on the top swing))Bottom bracket: no change it didn't seem worth itCrankset: Shimano Altus FC-M371 (48T/36T/26T) with crank arms (more top end on the 48t than the 42T)Pedals: MKS Allways EZY Superior (easy quick release pedals)Chain: Shimano CN-HG71 (8s, 7s, 6s, 116L)Freewheel, rear cogs: no change didn't seem worth it.Rear derailleur: Altus RD-M310 (7 / 8 speed compatible)Luggage rack: Topeak Tetrarack M2Now it's a pretty fun bike.

Directions are not clear and there is nothing online to clarify the directions. Heavier than expected but works as expected. Chain often slips off when changing gears and the bike doesn’t fold as expected.
