Having the best bike multi-tool can be a lifesaver in the woods and is an indispensable item for any mountain biker to have with them at all times.

Having a chain break while 10 miles back in the woods with no cell phone coverage is not out of the realm of possibility.

It’s not just mountain bikers that a multi tool can come in handy for. If you are a road biker who takes long trips, you can run into a situation where you need to make an emergency repair as well.

Bike Multi-Tool Reviews

#1 Topeak Alien II Multi Tool

The Topeak is the MacGyver of tools. I really don’t think there is a repair that you would need to make that the Alien II cannot handle.

The Topeak Alien is a high quality tool made from hardened, stainless steel that feels good in your hand. You can tell once you open it for the first time, it’s well-made.

As you can see it has most everything you would need plus it comes with a nice carry pouch that will fit in any seat cargo pack. The Topeak Alien II is a good option and might be the best bike multi tool for the money.

#2 Crank Brothers M19 Multi Bicycle Tool

Crank Brothers has been making cycling tools for quite some time and the 19 function multi tool is a good offering.

Unlike some other multi-tools the Crank Brothers does not split apart but being designed like a Swiss Army knife, it is very easy to use.

Definitely a higher grade tensile steel than most tools in its class, you can just about stand on it to turn a bold that is locked hard. It comes with just about every tool the biker can ask for to make repairs.

The tools fit securely in each size bolt or screw, a testament to its quality construction and tolerances.

The Crank Brothers M19 finishes off the complete package with a stainless steel carry case and is small and light enough to fit in your cargo pack or just keep it in your pocket. By far the Crank Brothers M19 is one of best cycling multi tools you can buy.

#3 Park Tool MT Multi-Tool

Park Tools are synonymous with quality. The MT is quality made here in the USA from high grade stainless steel so it will not rust.

The Park MT is a standard “switch blade” design that packs several tools into a compact tool that fits in your pocket.

This allow maximum usage of each tool, a great design in my opinion. It snaps back together securely so you don’t lose any of the pieces.

The only thing missing from this MTB multi tool is a carry case of some sort, but this is a minor detail in my book. I also would like to see a bottle opener like the Crank Brothers.

The Park Tool is a no brainer and you won’t go wrong taking this out in the woods for any emergency repairs. This is probably the best MTB multi tool you can buy.

#4 Lezyne Stainless 20 Multi Tool

The Lezyne bike tool has a simple elegant design. Made from high quality stainless steel in a Swiss Army style the tool has 20 functions to fix most any repair the mountain or road biker will need.

Unlike most other bike tools it comes with a razor sharp serrated edge knife. It can really come in handy when you need to cut something!

The Lezyne bike tool screams quality and is one best bike multi tools available. Its an easy to use tool that hopefully you won’t need to use it out in the woods but if you do, you will be glad you have it!

#5 Pro Bike Tool Multitool

The Pro Bike Tool is by far the smallest and lightest of the bike multi-tools evaluated. This is going to be more for use for road bikers because it lacks a few tools that a mountain biker would find critical.

They even pack a chain tool in this slim tool, and the tools it does provide are very high quality. Made from a high grade SUS420 stainless steel this tool will not rust like cheaper stainless steel tools.

In addition the tool’s surface has a anti-corrosion treatment. It has a simple Swiss Army knife design that is easy to use and very compact.

They include most any tool you are likely to use or need so if you are looking for an elegant, slim tool that will take care of most adjustments and repairs, the Pro Bike Tool is probably the best road bike multi tool.

How to Choose the Best Bike Multi Tool For You

What Bike Multi-Tool is Right For You?

We have a variety of tools for you to choose from is a variety of configurations:

All in One – These mult-tools have most every tool you could possibly need or want. Everything from allen wrenches, screw drivers and chain tools. The trade off is weight and bulk. They may barely fit in your under seat saddle bag. You may need to keep it in your backpack. The Park Tool is a good example of this type.

Minimalist – These multi-tools will be only able to make the simplest of repairs. Normally they only come with the most common Allen wrenches and flat head and Phillips screw driver. Under most circumstances this may be enough. The upside of these tools is the lightweight and small size. The Pro Bike Tool is a good example of a minimalist tool.

In the end it comes down to do you think you will just be making some simple adjustments or full on repairs in the field?

Multi-Tool Functions

Screw Drivers

Having both a flat head and a Philips is an absolute must. You will be hard pressed to find a bike that doesn’t have both types of screws somewhere on the bike.

Allen/Hex Wrench

Most every road and mountain bike have Allen screws on it whether it’s to adjust the brakes or the seat, you’re going to need this essential tool. More is definitely better as there are many sizes in use.

Chain Tool

Probably more crucial for the mountain biker but still a good idea for the road biker. If you need to remove a broken chain link, having a chain tool is an absolute necessity.

Torx

The use of Torx screws is becoming more common on bikes, especially on higher end bikes. Luckily the Torx 25 is pretty much the standard size.

Quality

You can buy a cheap bike multi-tool that may have all the necessary tools BUT here is the problem: If the tools are of poor quality they might break the first time you go to use it! I have seen it happen.

Not only may the tool break you may damage your bike by stripping a screw or bolt but possibly injure yourself. If you have ever scraped your knuckle because of a poor quality tool you know what I mean.

Weight and Size

Of course lighter is better but you can’t sacrifice strength to get it. The tool has to be sturdy enough to handle a tough job.

Size is important as well, you don’t want it too small because you won’t be able to get any leverage on the tool to turn a tough screw or bolt! Keep in mind if your carrying it a saddle bag, make sure you have enough room to fit it.

One other consider is a case. While it’s nice to keep the tool in a protective case, the trade off is extra size and bulk. If you are keeping the tool in an under seat saddle bag, you may not have room for a case.

Bike Multi-Tool FAQ

What is a bike multi-tool?

A bike multi-tool has all of the metric Allen keys and other tools needed for trail and roadside repairs and adjustments.

Do you need a bike multi-tool?

A set of metric Allen keys can adjust the bolts on your road or mountain bike. However, bike multi-tools include cycling-specific tools such as a chain breaker and T25 Torx wrench.

Do I need a chain tool on my multi-tool?

Not all bike multi-tools include a chain breaker. A chain breaker adds weight and size to multi-tools but comes in handy. Even if you’re not comfortable fixing your own chain, investing in a multi-tool with an integrated chain tool will allow fellow cyclists to help you if you break a chain on a ride

How should I carry a multi-tool while riding?

Multi-tools are designed to fit easily in a saddle bag, hydration pack, or jersey pocket.

Conclusion

There is a large difference in quality between the bike multi-tools. I have used quite a few over the years and can attest to this.

A good bike tool will allow you to do just about all common tasks and repairs on a bike. Such as adjusting your handlebars, seat height or brakes.

If you don’t have a full tool box at your home, then purchasing a multi-tool with all the functions and tools you might need is even more important.
