Best Bike Pedal Wrenches for Adult Tricycles
Five pedal wrenches compared for jaw size, handle length and leverage on stuck pedals.
Updated · 4 min read · 5 products evaluated
Pedals are not tightened to a torque number. A pedal goes in to roughly hand-tight plus a firm pull on the wrench, and that is enough because pedaling force tightens the threads. What matters is the tool and how you use it.
Two facts catch new owners out. The left pedal is reverse threaded, so it loosens clockwise when you face the crank. And a seized pedal needs leverage, which is why handle length is the main thing separating these wrenches.
Short answer
The Jaswill 4 in 1 is the best overall with a 320 mm handle, two 15 mm jaws and a 9/16 inch jaw. The groword is the near twin with a PVC coated handle. The Pawfly 3 in 1 adds crank puller and bottom bracket openings. The Nainsect has a slanted offset handle and 15, 16 and 17 mm sizes. The Mantain is the lowest cost and shortest handle.

Best Overall1 of 5
Jaswill 4 in 1 Pedal Wrench
A long 320 mm handle and the sizes most pedals need.
Best for
Seized pedals
Why we like it
It has two 15 mm spanners, one 9/16 inch spanner and three hex sockets of 6, 8 and 10 mm. The heavy-duty steel is 5 mm thick with a quenched heat treatment, and the 320 mm handle gives real leverage.
The long handle is the difference against the shorter Mantain and Nainsect, because a stuck pedal on a trike often takes a firm pull. It is too long for a seat bag. Match the jaw to your pedal flats; most are 15 mm, and the 9/16 inch jaw covers older pedals. It is a newer product with limited history.

Best PVC Handle2 of 5
groword 4 in 1 Pedal Wrench
The same layout as the Jaswill with a PVC coated grip.
Best for
Comfortable grip
Why we like it
It offers two 15 mm bayonets, one 9/16 inch bayonet and three hex sockets of 6, 8 and 10 mm. Laser cut jaws and a quenched finish give a tight fit, and a 320 mm PVC coated handle is non slip.
It is very close to the Jaswill, so the choice often comes down to grip and price. Size numbers are marked on the wrench, which helps when switching between ends. Check that the jaw you select seats fully on the pedal flats before applying force.

Best Multi Task3 of 5
Pawfly 3 in 1 Pedal Wrench
Pedal, crank puller and bottom bracket openings in one wrench.
Best for
Home mechanics
Why we like it
It has openings of 15 mm for pedals, 16 mm for crank pullers and 24 mm for bottom bracket tools, each marked with its size. The 5 mm high-carbon steel is 320 mm long with a rubber grip, and the surface is 3 layer electroplated.
It does more than the Jaswill, but has no 9/16 inch jaw and no hex sockets. The 16 and 24 mm openings suit crank and bottom bracket work, though you still need the matching extra tools. Confirm that your pedals are 15 mm before ordering.

Best Offset Handle4 of 5
Nainsect Double Sided Pedal Wrench
A slanted handle and three jaw sizes keep knuckles clear.
Best for
Knuckle clearance
Why we like it
It has double sided jaws of 15, 16 and 17 mm, a precision steel body and a plastic grip. The slightly slanted design helps keep knuckles away from the frame, and it is meant to be turned toward the front of the bike when installing.
The shorter handle gives less leverage than the 320 mm Jaswill, so a very stuck pedal may need a cheater bar or penetrating oil. It fits 15 mm pedals as well as the 16 and 17 mm sizes used on some pedals. The slant is a real help on a trike where the frame sits close to the pedal.

Lowest Cost5 of 5
Mantain Double Sided Pedal Wrench
A basic three size wrench for easy pedals.
Best for
Occasional use
Why we like it
It has three jaw sizes of 15, 16 and 17 mm, a carbon steel body with a rust resistant electrophoresis finish and a plastic grip.
It is the simplest and least costly here, with moderate length. Against the Nainsect it has no slanted handle and, against the 320 mm tools, less leverage. It suits pedals that come off easily, but a seized pedal may need a longer handle. It is a newer product with limited history.

How We Chose These Pedal Wrenches and Torque Tools
- Jaw size
- We checked for 15 mm, the common pedal size, and for 9/16 inch or 16 and 17 mm options. A wrench that does not seat fully on the flats rounds them off.
- Handle length
- We compared the 320 mm handles on the Jaswill, groword and Pawfly with the shorter offset tools. Longer handles give leverage for seized pedals, which is the usual trike problem.
- Material and grip
- We looked at thick steel and the PVC, rubber or plastic grips. A non slip grip and a 5 mm steel body help avoid slipping off the flats and scraping knuckles.
- Extra tasks
- We counted hex sockets, a 16 mm crank puller opening and a 24 mm bottom bracket opening as extras. They matter for home mechanics who want one tool for several jobs.
What to Look for in a Pedal Wrench
Thread direction
The right pedal has a normal thread, and the left pedal is reverse threaded. Facing the crank, the left loosens clockwise, so turning it the wrong way tightens it.
A useful rule is to turn the wrench toward the front of the trike to tighten and toward the back to loosen, on both sides. Test the direction gently before you apply force.
Jaw size
Most pedals use 15 mm flats, and some older or one piece crank pedals use 9/16 inch. A jaw that is slightly off can round the flats and make removal harder.
Check the flats on your pedal spindle and pick a wrench that matches. The Jaswill and groword carry both sizes, while the Pawfly has no 9/16 inch jaw.
Leverage
A longer handle multiplies the force you apply, and a stuck pedal needs it. A 320 mm tool does the work with less effort than a short one.
Penetrating oil on the threads helps, and a firm steady pull is better than a jerk. Check that the wrench is long enough to push with your body weight.
How tight to go
Pedals need roughly hand-tight plus a firm pull, not a torque number. Pedaling tightens them further, so there is no need to crank on the handle.
Add a light film of grease to the threads when installing so the next removal is easy. Check both pedals again after the first short ride.
Carrying size
A 320 mm handle does not fit a seat bag, so it lives in the garage. The 15, 16 and 17 mm offset tools are lighter and easier to carry for roadside work.
Decide whether you swap pedals at home or on the road, and choose handle length on that basis. Check the handle length against the space in your seat bag.
How to Choose
By Pedal Condition
| Situation | Our pick | Why |
|---|---|---|
| Seized pedal | Jaswill 4 in 1 Pedal Wrench | 320 mm handle gives the most leverage here |
| Seized pedal, softer grip | groword 4 in 1 Pedal Wrench | Same 320 mm leverage with a PVC coated grip |
| Tight frame clearance | Nainsect Double Sided Pedal Wrench | Offset slanted handle keeps knuckles clear |
| Also doing cranks | Pawfly 3 in 1 Pedal Wrench | Crank puller and bottom bracket openings in one tool |
| Easy pedals, occasional use | Mantain Double Sided Pedal Wrench | Basic 15, 16 and 17 mm jaws at the lowest cost |
Long Handle vs Short Handle
- Long
- The Jaswill, groword and Pawfly are 320 mm and give strong leverage for stuck pedals, but they do not fit a seat bag. They are best for garage use.
- Short
- The Nainsect and Mantain are easier to carry and have three jaw sizes, but they give less pull. They suit pedals that already turn freely.
Default to a 320 mm tool for home use.
For Seized Trike Pedals Specifically
- Look for
- A long handle, thick steel and a jaw that seats fully on the flats, so the force goes into the pedal and not into rounding the spindle.
- In this comparison
- The Jaswill 4 in 1 matches all three, with a 320 mm handle, 5 mm thick steel and 15 mm and 9/16 inch jaws, plus hex sockets.
When to Spend More
- Spend more if
- You do your own crank and bottom bracket work, where the Pawfly saves buying separate tools with its 16 mm and 24 mm openings.
- Save if
- You only swap pedals now and then, where the Mantain with 15, 16 and 17 mm jaws is enough.
Frequently Asked Questions
Do pedals need a torque wrench?
Not usually. Roughly hand-tight plus a firm pull on a pedal wrench is enough, and pedaling tightens them further. Grease the threads when you install them so they come off easily next time, and recheck after a short ride.
Which way does the left pedal turn?
The left pedal is reverse threaded, so it loosens clockwise when facing the crank. The right pedal uses a normal thread. Remember to turn the wrench toward the back of the trike to loosen on both sides.
What size is a pedal wrench?
Most pedals use 15 mm flats, and some older pedals use 9/16 inch. The Jaswill and groword carry both. The Nainsect and Mantain add 16 and 17 mm jaws. Check the flats on your spindle before you buy.
Why does a long handle help?
It multiplies the force you apply, which helps with a seized pedal. The 320 mm handles on the Jaswill, groword and Pawfly do the job with less effort than a short tool. A steady firm pull works better than a jerk.
Should I grease the threads?
Yes, a thin film of grease on the threads makes the next removal easier. Apply it to clean threads when installing the pedal. This matters most on a trike that sits outside or gets washed often.
Can a pedal wrench do other jobs?
Some can. The Pawfly adds a 16 mm crank puller opening and a 24 mm bottom bracket opening, and the Jaswill and groword include 6, 8 and 10 mm hex sockets. Check that the tool covers the sizes your trike uses.
Bottom Line
The Jaswill 4 in 1 is the best all round pedal wrench for trike owners, thanks to its 320 mm leverage and both 15 mm and 9/16 inch jaws. The Pawfly suits home mechanics who also work on cranks, and the Nainsect suits tight clearance. Check your pedal flats and thread direction before you start.
