Best Bike Phone Mounts Under $20 for Adult Tricycles
Four budget phone holders, and how silicone straps and a frame pouch behave on a trike.
Updated · 4 min read · 4 products evaluated
A trike rides over the same cracks as a bicycle but with three wheels hitting them, so vibration reaches the handlebar harder. A phone holder at this budget has to hold on a wide cruiser bar, cushion that buzz and keep the screen readable.
We compared four options: three silicone strap mounts and one frame pouch. Silicone straps are the easiest to fit, but they have no positive lock, so fit and case thickness matter.
Short answer
The Kinizuxi 2 pack is our top pick: two silicone mounts, 360 degree rotation and a fit for phones from 4.7 to 6.8 inches. The YTDSUP and MCOTOP are close alternates, with stated phone ranges of 4 to 6.7 and 4.7 to 6.9 inches. The ROCKBROS pouch suits riders who want a waterproof place for a phone and small items, but it needs a suitable frame tube.

Kinizuxi 2 Pack Silicone Phone Mounts
Two silicone mounts with a wide, clearly stated phone range.
Best for
Most riders
Why we like it
The Kinizuxi is a two-pack of silicone phone holders with 360 degree rotation. A silicone strap wraps around the phone and the handlebar like a wristwatch, so no tools are needed, and the flexible material takes the edge off vibration. It fits phones from 4.7 to 6.8 inches and thickness up to 15 mm including the case.
Compared with the YTDSUP and MCOTOP it has a clearly stated thickness limit, which is useful because a rugged case can exceed it. Two mounts also let you fit a second bike or trike. The trade-off is that a strap has no twist lock. Check strap tension before every ride.

Best Alternate2 of 4
YTDSUP 2 Pack Silicone Phone Mounts
A similar two-pack with horizontal and vertical modes.
Best for
Riders who switch orientation
Why we like it
The YTDSUP is another two-pack silicone holder with 360 degree rotation, horizontal and vertical modes and a quick-release strap. Its strap is upgraded for different phone sizes, with a stated range of 4 to 6.7 inches. The maker says it was pull tested, which is a claim to treat cautiously.
Against the Kinizuxi it covers smaller phones but the stated upper limit is slightly lower and it gives no thickness figure. It suits riders using maps who change orientation. Check that your case fits within the strap range.

Best for Large Phones3 of 4
MCOTOP Silicone Bike Phone Mount
The widest stated phone range of the set.
Best for
Large phones
Why we like it
The MCOTOP is a single silicone mount with 360 degree rotation and adjustable elastic straps. It is stated to fit phones from 4.7 to 6.9 inches including the case, and the makers say it also fits scooter handlebars, strollers and shopping carts.
Compared with the two-packs it is a single unit, which is fine if you need only one. Its strap fits any bar size by design, so check it wraps firmly around a wide cruiser bar. It has no stated thickness limit.

Best for Small Items4 of 4
ROCKBROS Frame Phone Bag
Waterproof pouch for a phone and small gear.
Best for
Riders carrying small items
Why we like it
The ROCKBROS is a frame bag with a sensitive TPU window, sealed double zippers, reflective tape and a hidden earphone hole. It fits phones below 7 inches and also holds keys, a wallet or a small repair kit, and it attaches with three hook-and-loop straps.
Unlike the strap mounts it carries items besides the phone, but it needs a frame tube to mount on, and a trike's step-through frame may offer none. The screen also sits low. Confirm a suitable tube exists before ordering.
Key specs
| Fit and mounting | Three hook-and-loop straps to the frame |

How We Chose These Bike Phone Mounts Under $20
- Phone fit
- Stated phone size ranges and thickness limits decided whether a mount works with your device, from the 4 inch low end of the YTDSUP to the 6.9 inch top of the MCOTOP.
- Vibration
- Silicone cushioning was weighed against rigid clamps, because shake on a rough path blurs the screen and can loosen a grip over time.
- Bar fit
- A mount must wrap a wide cruiser bar firmly, so strap reach and tension counted for more than the shape of the cradle.
- Weather
- Rain protection was considered, since only the ROCKBROS pouch has sealed zippers and the silicone mounts leave the phone open.
- Value in the box
- The two-pack Kinizuxi and YTDSUP were weighed against single mounts, because a second mount covers a second trike or a spouse's phone.
What to Look for in a Bike Phone Mount Under $20
Silicone strap vs clamp
A silicone strap wraps around the phone and bar and absorbs vibration, but it relies on tension. A rigid clamp locks positively but transmits more shake.
None of these mounts has a positive lock, so check strap tension before every ride and replace a stretched strap. Give the phone a firm tug before rolling off.
Phone size and case
Mounts quote a phone size range, and a thick case adds to the real size. The Kinizuxi sets a 15 mm thickness limit, so a rugged case can push a phone past what the straps can hold.
Measure your phone with its case and compare it with the range, such as 4.7 to 6.8 inches for the Kinizuxi. If the case is bulky, choose the mount with the larger range.
Handlebar diameter
A mount must grip the bar firmly. Wide cruiser bars need a longer strap, and a short one will stretch thin or not close at all.
Check the strap length or the stated bar range, and wrap the strap around the bar by hand when it arrives. The ROCKBROS needs a frame tube rather than the bar.
Weather protection
Silicone mounts leave the phone exposed to rain, while the ROCKBROS pouch has sealed zippers and a clear touchscreen window. A phone that gets wet may stop responding to touch.
Choose a pouch for wet routes or carry a cover. Check the touchscreen through the window before relying on it for navigation, because a thick film can dull taps.
Screen position on a trike
A trike rider sits upright with a flat handlebar, so a phone strapped to the bars sits in the line of sight. A frame pouch sits lower on the tube, which can put the screen below the ideal viewing angle.
Sit on the trike with the phone in place and see whether you can read it with a quick glance. If you need to look down, the position is not working.
How to Choose
By Phone Size
| Situation | Our pick | Why |
|---|---|---|
| Phone up to 6.8 inches with a case | Kinizuxi 2 Pack Silicone Phone Mounts | 15 mm thickness limit including the case. |
| Small phone of 4 inches | YTDSUP 2 Pack Silicone Phone Mounts | Range starts at 4 inches, with quick release. |
| Large phone around 6.9 inches | MCOTOP Silicone Bike Phone Mount | Widest range, up to 6.9 inches. |
| Phone under 7 inches plus keys | ROCKBROS Frame Phone Bag | Pouch holds small items and keeps rain off. |
Silicone Strap vs Frame Pouch
- Silicone strap
- Kinizuxi, YTDSUP and MCOTOP mount in seconds on the handlebar and cushion vibration. They leave the phone exposed to rain, so pair them with a cover.
- Frame pouch
- ROCKBROS protects the phone from rain and stores small items, using three hook-and-loop straps. It needs a suitable frame tube, and the screen sits low on a trike.
Most trike riders should default to a silicone strap unless the frame has a suitable tube.
For Maps and Navigation Specifically
- Look for
- Easy orientation changes and a screen in sight at a glance, so you are not looking down while steering.
- In this comparison
- The YTDSUP offers horizontal and vertical modes and the Kinizuxi rotates 360 degrees, both on the handlebar. The ROCKBROS keeps the screen lower.
When to Spend More
- Spend more if
- You ride rough paths daily, since the Kinizuxi, YTDSUP and MCOTOP lack a positive lock and the strap tension can slip.
- Save if
- You ride smooth paths and want a basic holder. The Kinizuxi two-pack covers two trikes or two phones for less effort.
Frequently Asked Questions
Will a silicone mount hold my phone on a rough path?
Strap tension matters. Check it before each ride, since none of these has a twist lock. On rough paths the phone can shift, so a quick tug before you roll helps. Replace a stretched strap rather than hoping it holds.
Do I need a different mount for a wide bar?
Check the strap reaches around the bar. All three strap mounts say they fit common handlebars, but a wide cruiser bar needs enough strap to stay snug. Wrap it by hand when it arrives to confirm the fit.
Will a thick case fit?
The Kinizuxi allows 15 mm including the case. The YTDSUP and MCOTOP do not give a thickness limit, so measure the case and check the fit with the phone in place before a ride, on a flat surface.
Does the ROCKBROS work on a step-through trike?
Only with a frame tube to strap to. Step-through frames often have a low or sloped tube, so check where the pouch would sit and whether you can read the screen at a glance before you rely on it.
Are these waterproof?
Only the ROCKBROS pouch has sealed zippers and a clear touchscreen window. The silicone mounts hold the phone open to the air, so use a cover for rain and keep the phone dry in a pocket when the weather turns.
Can I use the two-pack on two trikes?
Yes, the Kinizuxi and YTDSUP each include two mounts, so one can stay on each trike or on a spouse's. Both are tool-free, so moving a mount between bars takes only a minute and a firm strap check.
Bottom Line
The Kinizuxi is the best all-round pick at this budget, with a clear phone range and a 15 mm case limit. Choose the YTDSUP if you switch phone orientation, the MCOTOP for the largest phones or the ROCKBROS for a waterproof pouch if your frame has a tube.
