Q: How to assemble the pedals? Fully tighten the pedals!!! Fully tighten the pedals!!!
A: Installing Pedals
1. Identify Left vs Right pedal. There is a "L" or "R" stamped into the spindle of the pedals. make sure they are assembled on the right side(when you ride on the bike, left pedal on your left hand, right pedal on your right hand).
2. Install the left hand pedal first. You will have to screw it in COUNTER-CLOCKWISE because the threading is the reverse of a normal screw. DO NOT USE THE WRENCH until you are ready to tighten it for the final few turns. Tighten it down until you can't anymore. (If you feel you do not have enough hand strength you can slide a pipe over the wrench to extend the lever and get more force but be careful not to bend the wrench)
*Notice* If the pedals are not fully tightened, it may get loose and damage the threads, we will NOT be responsible for such damages.
3. Install the right hand pedal. This one threads in CLOCKWISE, like a normal screw. Follow the same principals as discussed in step 2 for the left pedal.
Q: How to assemble front wheel?
1. Rotate the fork for 180 degree before assemble the front wheel (Make Sure the brake/bracket will be in front of the bike)
2. All merax bikes have quick-release front wheels, the wheel should be assembled with the quick relase pin

Q:The Chainring teech is "broken"
There is NOTHING wrong with your chainring teech, Chainring teeth have different shapes and profiles all the way around the ring. usually a chainring is divided into 2 180* halves, and the shape of the teeth will change almost every tooth, some teeth are shorter by design, in order to facilitate shifting up.
HOW TO CARE FOR YOUR BIKE
The maintenance schedule for a bike can vary somewhat on how often it's ridden and what condition it's in to begin with. Bikes that are ridden off-road or in the rain will need a little more TLC than one that ventures over the Brooklyn Bridge once per month.
However, using the following guidelines will help keep a bike good working condition - and help you know when it's time to bring it in to a mechanic.
These tips require a few basic tools (allen key, wrench, bike lube and de-greaser.) We sell these in-shop, if you need them. And: Don't forget a good bike pump, to keep air in your tires!
Bike care tips:
Keep your bike inside; avoid storing it outside. Weather's water and dirt will combine to cause harsh wear and cost you more in repairs and service.
Bicycles ridden in rain and/or off-road typically require more frequent and extensive service. If you are a frequent commuter or distance rider, you may find that your bike needs service more often. Probably because you're having more fun. Nice work!
Don't use WD40 on your chain!! WD-40 is made for doors and things that move sometimes, not bikes - which have lots of pressure and movement. In fact, WD40 will actually strip your chain of oil, causing metal-on-metal grinding.
If your bike has been crashed, or you purchased a used bike, we recommend bringing it in for a thorough check-up to ensure that it's running properly. Where parts connect or move, if instead of turning or moving they instead "wobble" or creak, something is likely in need of attention. Bring it in - we're happy to take a look.
Enjoy it! The #1 goal of a bike should be to provide transport and fun. If these details overwhelm you, just focus on the "every ride" section in the left column! Our mechanics are happy to answer questions if you feel in over your head. If you want to learn more, we invite you to check out our maintenance and repair classes!

(or 2,500 miles)
(or 6,000 miles)
check tire pressure. if it's low (if the tire feels "squishy"), fill to the correct PSI - which is listed on side of your tire.
clean bicycle frame with a cloth.
inspect frame and components for signs of wear, such as cracks or dents.
clean and wax the frame to protect the paint/finish.
once it's clean, inspect bike frame and fork for any cracks or dents.
check all bearing systems: hubs, bottom bracket, headset and pedals.
adjust and/or overhaul as needed, based on their condition.
glance over the tire tread on both tires for embedded debris, to avoid getting a flat.
wipe the chain and cassette cogs clean with a rag + earth-friendly degreaser.
re-lube chain, casette.
check tires for wear such as dry rot or areas where tread is now too worn. replace if cracks or wear are significant.
check your spare tube and patch kit: make sure the spare still holds air and the patch kit has glue + patches.
check all brake and gear cables + cable housing for fraying, breakage, rust, corrosion.
replace if necessary.
if you have quick release parts (such as wheels or seats, instead of nut/bolt), check that they are tight and that the wheels are secure
check the wheels for loose spokes. if the spokes are loose, you may need to replace them. (this is pretty inexpensive.)
check the condition of hubs, bottom bracket, headset. adjust and/or overhaul as needed.
replace brake pads, rubber brake hoods and handlebar tape if necessary
spin wheels to check for wobbles. if the wheel wobbles (instead of rolling smoothly), this indicates that you need to have your wheel trued
using a wrench, test the tightness of the moving and connecting parts: crankarms, pedals, chainring bolts, seat bolt, seatpost bolt, stem bolts, handlebar bolts and all accessory mounting bolts/screws. you are checking to be sure all parts connect properly.
check all cables and housings for fraying, breaks, rust and corrosion and replace if necessary
clean and check wheels carefully for signs of wear such as worn sidewalls or cracks where the spoke touches the rim or hub
squeeze brakes to make sure they're grabbing
glance over brake pads to see that they are in good condition and that they touch the rims (not the tires!)
lube the brake, derailleur and pedal pivot points.
check for worn brake pads and replace if needed; also replace worn handlebar tape or grips
check the hubs, bottom bracket, headset: adjust and/or overhaul as needed
if you have a mountain bike, push down on (compress) and release the bike's suspension to be sure that it's responding properly
lube the brake and gear cables to prevent binding.
check the cables for fraying and rusting. replace if necessary
check for chain, cassette cog and chainring wear and replace worn parts as needed
overhaul the pedals to check the bearings and add fresh grease. (this can be tricky!)
if you're using toe straps, check them for wear and replace if needed.
look over the bike chain. add chain lube if it looks dry.
check clipless pedals and cleats for loose screws/bolts
clean the drivetrain (chain, chainrings, cassette, front and rear derailleurs) with biodegradable solvent and rags
maintain and lube your suspension components according to the advice in the owner's manual
make sure you are prepared with tools (a spare tube and/or patch kit, tire levers and a pump), in case you encounter a flat while riding. or, that you are close to a bike shop who can do it for you.
if you have a mountain bike, maintain and lube your suspension
if you have a mountain bike, maintain and lube your suspension components
lube your frame and home tire pump
check basket, racks and accessories - be sure attachments and bolts seem in OK condition.
