Essential Cycling Accessories: Locks, Bags, Lights, Mounts and Bike Computers

Stepping into the world of cycling involves more than just the bike itself. The right cycling accessories can transform your experience, making every ride safer, more practical, and far more enjoyable. While it’s easy to get overwhelmed by the options, focusing on a few key categories will set you up for success, whether you’re commuting, running errands, or riding for fitness. This guide will walk you through the essentials, explaining what they do and how to choose them without the need for brand names or complex jargon.

Essential Cycling Accessories for Security and Convenience

Think of accessories as your bike’s support system. They don’t make the bike go, but they solve the problems that come with using it in the real world. From preventing theft to carrying your lunch, these tools help you integrate cycling smoothly into your life. Before diving into specific gear, it’s a good idea to understand the broader landscape of cycling gear for beginners to prioritize your purchases.

Bike Locks: Protecting Your Investment

A lock isn’t an optional extra; it’s a necessity if you plan to leave your bike anywhere, even for a minute. The goal is to make your bike a less appealing target than the one next to it.

Your locking technique is as important as the lock itself. Always secure the frame and at least one wheel to a fixed, immovable object. If you have quick-release wheels, either use a lock long enough to include them or consider secondary security for them. For maximum security, many riders use two different types of locks, like a U-lock and a cable, to require more tools to steal the bike.

Bike Bags and Racks: Carry Your Gear

Free up your back and ride more comfortably by letting your bike carry the load. Bags attach directly to your bike, while racks provide a platform for strapping items or attaching larger bags.

• Frame Bags: Fit inside the main triangle of the frame, great for tools, snacks, and small items.
• Saddle Bags: Mount under the saddle, perfect for a compact repair kit, spare tube, and tire levers.
• Handlebar Bags: Offer easy access to items like your phone, keys, or a map during the ride.
• Panniers: These are larger bags that attach to a rack over the rear (or front) wheel. They are ideal for commuting, grocery runs, or longer trips.
• Bike Racks: A rear rack is a versatile foundation. You can bungee a backpack or box to it, or use it with panniers. Ensure your bike has mounting points for a rack if you choose this route.

Accessories for Navigation and Hydration

Staying on course and hydrated are two fundamentals for any ride. Simple accessories solve these needs elegantly.

Phone Mounts: Secure Navigation

Using your smartphone for navigation or tracking your ride is common, but holding it in your hand is unsafe. A handlebar mount secures your phone where you can see it. Look for a mount that holds your specific phone model snugly, is easy to install, and protects your phone from vibration and the elements. Always check the manufacturer’s instructions for secure attachment.

Water Bottle Cages: Easy Access to Fluids

Staying hydrated is critical. A simple bottle cage mounted to your frame allows you to carry a water bottle and grab it without stopping. Most bikes have mounting holes for at least one cage. They are typically made of lightweight metal or plastic. Just ensure the cage fits the size of bottle you prefer to use.

Bike Lights: See and Be Seen

Lights are a critical safety accessory, not just for night riding but for any low-light condition like dawn, dusk, fog, or rain. A front light helps you see the road ahead, while a rear light makes you visible to traffic from behind.

Always ensure your lights are charged before a ride. For commuting, consider lights with a USB rechargeable battery. Remember, lights are a complement to, not a replacement for, reflective clothing and a properly fitted helmet. For more on the most important safety gear, see our bike helmet buying guide.

Bike Computers vs. Phone Apps

If you’re interested in tracking your speed, distance, route, or fitness progress, you have two main options: a dedicated bike computer or a smartphone app.

• Bike Computers: These are dedicated devices that mount to your handlebars. They are designed to be rugged, weatherproof, and have long battery life. They connect to sensors (like for heart rate or cadence) and provide clear, glanceable data, often with screens readable in direct sunlight.
• Smartphone Apps: Your phone can run powerful cycling apps that use GPS to map your ride and record data. This is a low-cost way to start. However, it uses your phone’s battery quickly, the screen can be hard to see in sun, and you risk damaging your phone from vibration or weather if not well-protected in a mount.

The choice depends on your needs. If you ride frequently, want detailed data, and don’t want to drain your phone, a bike computer is a dedicated tool for the job. If you’re just starting out and want to try tracking, a phone app is a great first step. For longer rides, consider pairing either with appropriate cycling clothing for comfort.

Frequently Asked Questions

What is the most important cycling accessory to buy first?

After a helmet, a good lock is arguably the most critical accessory if you ever leave your bike unattended. If you only ride in secure areas, then front and rear lights are the top priority for safety, as they are essential for being seen in any low-light condition.

Can I use a backpack instead of bike bags?

You can, but a sweaty back and shifted weight can make riding less comfortable, especially on longer trips. Bike bags and racks distribute the weight onto the bike, improving balance and comfort. For short commutes, a backpack is fine, but for heavier loads or longer distances, on-bike storage is highly recommended.

Are cheap bike locks worth it?

A very inexpensive cable or low-security lock may only deter the most casual opportunist. For real protection, invest in a lock with a solid security rating. Think of it as insurance for your bike. Using a robust lock with a proper technique is the best deterrent against theft.

Do I need a bike computer if I have a smartphone?

Not necessarily. A smartphone app is a perfect tool for beginners to explore ride tracking. However, if you find yourself riding more often, wanting to conserve phone battery, or needing a more durable and readable display, a dedicated bike computer becomes a worthwhile upgrade.

How many water bottles should I carry?

For most casual or fitness rides under an hour, one bottle is sufficient. For longer rides, hotter weather, or more intense efforts, plan for two bottles or plan a route where you can refill. Hydration needs vary, so it’s better to start with the capacity for more. Explore our full bike accessories category for more detailed guides on specific products.
