Choosing the best mountain bike accessories depends on your specific needs for safety, maintenance, and comfort. Whether you prioritize trailside repairs or visibility, balancing weight and utility is key. The Ascher USB Bike Lights and Crankbrothers M19 Multi-Tool are the two most common starting points for most cyclists.
1. Ascher Ultra Bright USB Rechargeable Bike Light Set
Best for: Riders who commute or hit trails after the sun sets.
This set provides both a front headlight and a rear taillight, which are essential for being seen by others. The lights feature four modes to help you adapt to different environments, from pitch-black trails to busy city streets. With a 2000 mAh front battery and 330 mAh rear battery, they offer between 5 to 16 hours of light depending on the selected mode.
The IPX4 water-resistant rating means you can ride through rain or snow without worrying about the electronics. Installation is simple with silicone straps that fit most handlebars and seat posts without needing any tools. This isn’t for a rider who wants a permanent, wired-in lighting system, as these are portable units meant for quick attachment and removal.
Good if:
- You ride in low-light conditions regularly.
- You need a tool-free installation process.
- You want to keep your bike lightweight and portable.
Skip it if:
- You require a permanent lighting solution.
- You need extreme, long-range illumination for professional racing.
2. Crankbrothers Multi Tool M 19 Matte Black
Best for: Solving mechanical issues while out on the trail.
This tool packs a wide variety of hex wrenches, screwdrivers, and spoke wrenches into a slim 89mm frame. It includes a chain tool compatible with 8 to 12-speed chains, which is vital if you experience a snapped chain miles from home. The side grips are designed to be ergonomic, allowing for a secure hold even when wearing gloves.
Because this tool is built to be compact and lightweight at 175g, it’s easy to carry in a jersey pocket or a small saddlebag. It isn’t for the home mechanic looking for a full set of shop-grade tools, as the small size prioritizes portability over the leverage a full-sized wrench provides. It comes with a lifetime warranty to cover any manufacturing defects.
Good if:
- You want to be prepared for common trailside mechanicals.
- You need a chain tool in your kit.
- You prefer gear backed by a long-term warranty.
Skip it if:
- You’re looking for a complete shop-grade toolset.
- You have very large hands and struggle with compact tools.
3. BV Bicycle Pump Durable Bike Floor Pump 17/24 inch Smart
Best for: Quick and accurate tire pressure maintenance at home.
Maintaining correct tire pressure is the easiest way to improve your ride quality and prevent flats. This pump features a 160 PSI capacity and a smart valve head that automatically adjusts between Presta and Schrader valves. The handle is ergonomically designed to make the pumping action more comfortable during use.
At 16.25 inches tall, it’s small enough to store easily in a garage or shed. It isn’t intended for high-volume tubeless tire seating, as it’s designed primarily for standard maintenance. The listing doesn’t mention the scope of customer service support.
Good if:
- You want a simple, reliable home maintenance tool.
- You use both Presta and Schrader valve types.
- You need to reach high pressures with minimal effort.
Skip it if:
- You need to seat wide tubeless tires rapidly.
- You want a gauge that’s positioned at the top of the unit.
4. ROCKBROS Bike Saddle Bag Under Seat 3D Shell Bicycle Seat
Best for: Carrying small essentials like keys and repair tools.
This 3D shell bag protects your items with a shock-resistant design. It’s built from waterproof fabric with taped zippers to keep your gear dry during wet rides, though it shouldn’t be submerged. The bag attaches securely to your seat post using straps and a rubber buckle for a stable fit.
It includes internal mesh pockets to keep your items organized so they don’t rattle while you ride. There’s also a dedicated hook for a taillight to increase your visibility. It isn’t for those who need to carry large items like extra clothing or bulky spare tubes, as the space is compact.
Good if:
- You need a secure place for keys and snacks.
- You want a bag that offers some weather protection.
- You prefer a sleek, compact look under your seat.
Skip it if:
- You need to store multiple spare tubes or tools.
- You prefer a frame bag over a saddle-mounted bag.
5. Wittkop Bike Grips With Innovative 3-Zone Design Made in Germany
Best for: Cyclists suffering from persistent wrist pain or hand fatigue during long rides.
These grips feature an innovative 3-zone design intended to distribute pressure across your palms. The surface includes a non-slip area, a comfort zone, and an EFC area to ensure your hands remain stable. If you find your wrists aching after a short trip, this ergonomic shape is designed to correct your hand position.
The material is engineered to be weather-resistant, maintaining its integrity even when exposed to harsh UV rays. You can complete the setup quickly, as every pair includes the necessary hex key for a hassle-free installation.
These grips aren’t suitable for riders who prefer a thin, minimalist feel, as the ergonomic shape adds significant bulk to the handlebar.
Good if:
- You experience discomfort during longer rides.
- You want a durable, weather-resistant grip.
- You prefer a simple, tool-based installation.
Skip it if:
- You prefer the feel of traditional round grips.
- You’re looking for ultra-lightweight racing components.
6. CamelBak Podium Dirt Series Chill Insulated Mountain Bike Water Bottle
Best for: Keeping water clean and cold on muddy trails.
This bottle features an integrated mud cap that keeps the nozzle free of trail debris. The double-wall insulation helps keep your drink colder for longer than standard bottles. It’s designed to fit most standard bike cages, which helps ensure it stays in place on bumpy, uneven ground.
If your ride involves high-speed descents or technical rock gardens, the secure fit prevents the bottle from rattling or ejecting. When the trail turns messy, the mud cap is your primary defense against grit entering your water supply. Rely on the self-sealing cap for high flow, but remember to keep the cap closed when not in use to maintain peak insulation.
All parts of the bottle are easy to take apart, which makes cleaning out mud or dust straightforward. If you notice a lingering taste or visible residue after a wet ride, separate the cap components to ensure a thorough scrub. It isn’t for riders who prefer a hydration pack, as this is a frame-mounted bottle solution.
Good if:
- You ride in dusty or muddy conditions.
- You want your water to stay cold for hours.
- You value easy cleaning after every ride.
Skip it if:
- You prefer drinking from a hose-based hydration pack.
- You need a larger water capacity than 21 ounces.
7. Adjustable Bike Fenders
Best for: Staying clean when riding in wet or muddy conditions.
These fenders block spray from both the front and rear wheels to keep your back and clothes clean. The rear fender features a two-stage adjustable bracket that allows you to change the angle to suit your specific bike frame. They’re made from a thick, durable PP material that’s designed to resist cracking.
The quick-release design allows you to remove them when you want to ride in dry conditions. They aren’t for riders who want a permanent, high-end mountain bike mudguard system, as these focus on adjustability and ease of use. They fit most bikes with 20 to 26-inch wheels.
Good if:
- You commute or ride on wet, muddy trails.
- You want the ability to remove fenders quickly.
- You need a custom angle for your rear fender.
Skip it if:
- You ride bikes with very large wheel diameters.
- You want a permanent, fixed-mount fender system.
Where These Overlap
Most of these accessories focus on improving the comfort, safety, or maintenance of your ride. The Ascher USB Bike Lights and the ROCKBROS Saddle Bag both work to improve your experience on the trail by adding visibility, though they serve different functions. The Crankbrothers M19 Multi-Tool and the BV Floor Pump are both maintenance-focused, but the tool is for the trail while the pump is for the garage.
The Wittkop Bike Grips and CamelBak Podium Dirt bottle are both about rider comfort, ensuring you stay physically comfortable and hydrated. If you’re deciding between these, think about what is currently causing you the most trouble on your rides. If you’re getting dirty, look at the fenders; if you’re uncomfortable, look at the grips.
The listing doesn’t mention the skill level required for installation. Many feature quick-release or tool-free designs, such as the Ascher light’s silicone strap or the wedfish fenders’ hand-tightened knobs.
Still Not Sure?
How often do I really need to perform repairs?
If you’re a casual rider, you might rarely need a tool, but when you do, it’s essential. A multi-tool like the Crankbrothers M19 Multi-Tool ensures you’re never stranded with a simple mechanical problem. If you ride every single day, you’ll eventually face a loose bolt or a chain issue, making a reliable tool a necessity rather than a luxury for your kit.
Do I need to worry about compatibility?
Most of these items are designed to be universal, but you should always check your bike’s specifications before buying. For example, the BV Floor Pump uses a smart head that handles most valves, but ensure your tires use Presta or Schrader. If you need a specific fit for your seat post, the Adjustable Bike Fenders offer the most flexibility to ensure they mount correctly to your frame.
What is the biggest mistake I could make?
The biggest mistake is choosing gear that doesn’t match your riding style. If you only ride on paved paths, you may not need the mud protection of the Adjustable Bike Fenders or the nozzle protection of the CamelBak Podium Dirt. Think about your local trails and weather conditions, then choose the product that solves your biggest annoyance, such as using the Ascher USB Bike Lights for night visibility.
Frequently Asked Questions
Which bike pump is best for a beginner?
A beginner should look for a pump that’s easy to use and versatile, such as the BV Floor Pump. It features a smart valve head that automatically adjusts to your tire’s valve, removing the need for separate adapters or complex settings. Always follow the tire pressure guidelines provided by the tire manufacturer to ensure you’re inflating to the correct level for your specific terrain.
Can I install these accessories by myself?
Yes, all these accessories are designed for easy, tool-free or minimal-tool installation. For instance, the Ascher USB Bike Lights use simple silicone straps, and the Wittkop Bike Grips include the necessary hex key in the package. If you feel unsure, take your time to read the instructions provided in the box, as most of these products prioritize a quick setup process for the average rider.
How do I know if these grips will fit my bike?
Most modern mountain bike handlebars have a standard diameter, but you should verify your specific handlebar size if it’s an older or non-standard model. The Wittkop Bike Grips are designed for standard bars and come with an easy-to-use hex key to secure them in place. If your handlebars have a unique shape or unusual thickness, check your bike’s owner manual to confirm the diameter before you make your final selection.
Will the saddle bag get in the way of my pedaling?
The ROCKBROS Saddle Bag is designed to be compact and tucks neatly under the seat to avoid interference with your legs while you pedal. Because it uses a secure strapping system, it stays in place even on rough terrain.
Closing
Selecting the right gear comes down to whether you prioritize safety and convenience or comfort and maintenance. If your primary goal is to stay visible and prepared for minor mechanicals, the Ascher USB Bike Lights and the Crankbrothers M19 Multi-Tool will serve you well.
If you struggle with comfort, look to the Wittkop grips, which use a 3-zone design. For those dealing with messy commutes, the wedfish fenders offer a two-stage adjustable bracket to block spray. If you find yourself stranded by flat tires, the BV floor pump’s 160 PSI capacity and twin-valve design provide a reliable fix.
Take a moment to assess which part of your ride causes the most frustration. Start your upgrade there to ensure every mile is better than the last.
