What is the minimum order quantity for your bicycle factory? How many colors? Answer Our minimum order quantity is 100 units. A 20-foot container is recommended.Must be the same bike, but there can be one and two colors.
I have some bad news for you: The days of “pasta parties” are over. Unless your ride will be more than a couple of hours, you can stick to your normal diet the day before. You don’t want to eat too heavily before you head out, either. Good breakfast options should have a decent amount of carbohydrates and not be too rich in fats. We love eggs on toast, nut butter stirred into oatmeal, or a PB&J.
Measuring for chain wear is done with a chain checking tool or accurate ruler/tape measure. Which method you should use is the cause of much internet debate.Using a ruler, a new chain should measure exactly 12 inches across 12 links, from middle of pin to middle of pin. The number most commonly agreed on for a worn chain is one percent elongation between links. In reality though, you want to replace the chain before this point.So therefore anything past 12, 1/16 inches (0.5 percent) would be the time to replace a chain. And anything past 12, 1/8inches (one percent) has been worn to death and so a new cassette is likely needed.Holding a ruler perfectly straight while lining it up to measure 1/8in is difficult, and with this, chain checker tools provide a far simpler and quicker 'go or no-go' result. Whichever way you choose to measure a chain, be sure to not include any Masterlink, quicklink or 'Powerlock' which may be installed. Jones brings up the point that the parameters for chain wear have changed as drivetrains have. “Through the years, the replacement standards have changed," he says. "The chains are narrower now, and people are not weaker. Chains don’t last like they used to. Add to this rear sprockets are narrower and think don’t last like they used to. With six- to seven-speed (chains) a one percent wear was the norm, but that is no longer the case.” Countering Jones’ comment to some extent, Murdick claims the latest Shimano 11-speed chains are far more durable and resistant to length growth compared with previous generation 10-speed and earlier chains.
Chain wear is commonly referred to as ‘chain stretch’, because the chain’s pitch grows in length as it wears. This is the most important type of chain wear, and the growth comes from the bushings wearing with the chain pins. Overtime, the inner diameter of these bushings increase and the pins groove out.It’s often stated that a worn chain is when it reaches one percent growth from the original 0.5in (12.7mm) pitch.Another type of chain is wear is ‘slop’. This isn’t as easy to measure, but this side to side chain wear will lead to slow and inconsistent shifting long before any pin wear is seen.
Exactly how much wear your chain has will dictate your available options. On terribly worn drivetrains, the teeth of the cogs will begin to look hooked from the chain wearing high on them. If you’re at this point, replacing just the chain simply isn't an option.Some riders will choose to just let everything wear out until their bike starts skipping gears, but your risk of a snapped chain increases with this. Others will replace chain and cassette, and hope the chainrings are in a re-usable condition. If you do this, any shifting issues, chain suck (where the chain doesn't disengage from the bottom of the chainring) or chain dropping will signal that the chainrings aren’t happy. “If you're running a basic stamped steel cassette you could probably go past one percent wear and be fine," says Quade. "[But] if you're using an aluminium weight-weenie cassette it could be toast at a 0.5 measurement – the important thing to do is to test your bike after a chain swap."When the cassette is worn to the point it won’t mesh with a new chain, it can create a safety issue. So a [quick] spin after you've swapped the chain is never a bad idea. Never allow a new chain to wear into a worn cassette.”
There are many factors to choosing the right size bicycle. Arm, torso and leg length plus fitness level and flexibility are very important factors in the sizing process. For this reason, visiting your local dealer to fit you to a bicycle and provide test rides to ensure comfort and safety is the best way to get you on the proper size bike.
It varies. You should think of your purchase as the beginning of a long (and hopefully happy) relationship with your local bike shop. This means you’ll probably bring your bike in a few times a year for servicing and repairs. Some shops include a level of service with the purchase of a bike; you should ask about your shop’s policy. You should also find out what the manufacturer’s warranty covers. Often frames are covered “under normal use” which doesn’t include damage from crashes. Finally, ask about whether the shop will help you navigate the warranty process or whether you’ll be on your own.
Take your bike to your local bike shop for a quick safety check. They can determine if it is safe to ride or needs any additional maintenance. Ask them for an estimate first before the work is done. They can call you if they discover something major in the inspection process. The cost of a basic tune-up is approximately $50 to $75. Don’t assume just because you haven’t ridden your bike that it is still tuned-up. Grease and chain lubrication can dry over time, and cables can loosen up if bumped or moved around.
Be safe. Safety First! Always obey the rules of the road. Obey all traffic signals, signs, and laws. Get in the mindset of “driving” your bike—not just “riding” your bike. This will help you be a more focused and legally compliant bike rider. Wear a helmet for every ride, even short trips.Be predictable. Ride so drivers, other cyclists, and pedestrians can see you and predict your movements.Be alert. Ride defensively and expect the unexpected. Focus on riding and what is around you at all times. Always check behind you; do a quick check before you change lanes.Be equipped. Always maintain a safe bike, have a front bike light that works and a rear reflector, wear bright colored or reflective clothing so you are visible at all times, and carry tools to fix a flat.Be courteous. Yield to pedestrians and use hand signals to indicate to motorists your direction of travel.
Do I need special clothing to ride to work? If you are only riding a short distance, less than a mile commuting or to get around the campus, you can comfortably ride in your work clothes with the following notes: Use a pant-leg band to prevent your pants from catching in the chain. Refrain from riding in heels or a skirt/dress with loose or long fabric, as the fabric can get caught in the spokes and stop the bike immediately, posing a hazard. Also, be aware of loose straps from a backpack that may dangle into the chain.When riding longer distances, you may work up a sweat and might be more comfortable in bike shorts or bike pants and a jersey that will wick the moisture away to keep you dry. Make sure you wear proper footwear, flat soled shoes, and no open-toe sandals that leave your feet exposed.Remember: Wear a bike helmet for every ride!
How can I tell if my helmet is old and I need a new one? Helmets should be inspected before a ride. Look for cracks or dents in the foam or the foam degrading or crumbling—these are sure signs that it is time for a new helmet. Helmets should last approximately three years, but if you ever crash or drop your helmet, it is strongly recommended you replace it. Check the buckles to ensure a safe fit, and make sure the helmet is properly fitted, covering the forehead and not tilted back. Any local bike shop can check the fit to make sure it is correct.
What rules should I follow when riding my bike? Bicyclists need to follow the rules of the road as outlined by the California Vehicle Code,You may be cited for running stop signs, riding at an unsafe speed for conditions, riding on the wrong side of the road or on sidewalks, wearing headphones over both ears while riding, not having legal brakes and lights, etc. Cyclists are required by state law to use front white lights, rear red reflectors, and pedal and side reflectors at night. Additional lights, especially rear red flashers, extra reflectors, and light colored clothing are a good idea. We also recommend that you not talk on a cell phone or text while riding.While riding your bicycle, obey all traffic laws and wear a bicycle helmet for every ride, even short trips. Helmets can greatly reduce the risk of head injuries and death. In addition, defensive cycling is a key to bicycle safety. According to the California Vehicle Code, every person riding a bicycle on a street or highway has all the rights and responsibilities of the driver of a vehicle.
just like getting soaked, a puncture is a rare event that’s nevertheless very annoying. The best prevention is to use puncture-resistant tyres. These have layers under the tread that prevent bits of glass and the like from getting through to the inner tube.The best puncture-proof tyres for commuting use — such as the highly-rated Schwalbe Marathon Plus — practically eliminate punctures.You can also protect yourself by simply looking where you’re going. Ride around patches of broken glass, not through them, and avoid sharp-edged potholes that can cause a puncture by pinching the tube between tyre and rim. Fair-weather riders will find they get hardly any punctures anyway.Dry rubber is fairly tough stuff, but water on the road acts like a cutting lubricant and helps a shard of glass get through the tyre. It’s not that punctures are just more inconvenient and annoying when it’s raining, they’re also more likely!
It might surprise you to hear that cycling’s not especially dangerous. But what about all those stories about cyclists getting killed that you see on the news? Thing is, news is about rare events. Cyclist deaths are rare, so they make the news. The far higher number of pedestrian and motor vehicle deaths don’t.Cycling is statistically safe. “Per year, there are 10 to 15 fatalities due to people falling off bikes with no other vehicle involved,” says safety expert and co-author of Health on the Move, Malcolm Wardlaw. "Around 200 under-65s each year die in falls while walking. I don’t remember the last time I read a newspaper report of a pedestrian killed falling down steps, yet far rarer cases of cyclists killed in falls get a lot of media coverage — together with whether the cyclist was wearing a helmet or not.”The perception of cycling risk doesn’t match the realityEven when you throw motor vehicles into the mix, cycling remains stubbornly safe. It’s a little more risky than driving in the UK, taken as an average, but not much. The vast number of very safe motorway miles covered by British drivers skews the stats in the car’s favour too. And it’s not like UK cycle commuters are constantly running the gauntlet compared with their counterparts in the Netherlands. “Minority status generates fear,” says Wardlaw.John Franklin, cycling skills expert and author of Cyclecraft, agrees that the perception of cycling risk doesn’t match the reality. “There’s nothing in life that’s risk free,” he says. “It’s about the management of risk, not simply the fear of risk. As a cycle commuter, managing risk means being assertive, and behaving like traffic so that others will treat you as traffic.”
