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 · 3 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 |
|---|---|
| Features | Waterproof, touchscreen window, earphone hole |
Specs can change between model years; confirm the exact version before buying.
Strengths

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.
- Vibration
- Silicone cushioning was weighed against rigid clamps.
- Bar fit
- A mount must wrap a wide cruiser bar firmly.
- Weather
- Rain protection was considered for the pouch.
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.
Check strap tension before every ride and replace stretched straps.
Phone size and case
Mounts quote a phone size range. A thick case adds to that size.
Measure your phone with its case and compare.
Handlebar diameter
A mount must grip the bar firmly. Wide cruiser bars need a longer strap.
Check the strap length or bar range.
Weather protection
Silicone mounts leave the phone exposed to rain while a pouch protects it.
Choose a pouch for wet routes or carry a cover.
How to Choose
By Phone Size
| Situation | Our pick | Why |
|---|---|---|
| Phone up to 6.8 inches with a stated thickness | Kinizuxi 2 Pack Silicone Phone Mounts | 15 mm limit including case |
| Small phone of 4 inches | YTDSUP 2 Pack Silicone Phone Mounts | Range starts at 4 inches |
| Large phone around 6.9 inches | MCOTOP Silicone Bike Phone Mount | Fits up to 6.9 inches |
| Phone under 7 inches plus keys | ROCKBROS Frame Phone Bag | Pouch holds small items |
Silicone Strap vs Frame Pouch
- Silicone strap
- Kinizuxi, YTDSUP and MCOTOP mount in seconds on the handlebar and cushion vibration.
- Frame pouch
- ROCKBROS protects the phone from rain and stores items, but needs a frame tube.
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.
- In this comparison
- The YTDSUP and Kinizuxi rotate 360 degrees and sit on the handlebar.
When to Spend More
- Spend more if
- you ride rough paths daily, since the Kinizuxi, YTDSUP and MCOTOP lack a positive lock.
- Save if
- you ride smooth paths and want a basic holder, where the Kinizuxi two-pack covers two trikes.
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.
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.
Will a thick case fit?
The Kinizuxi allows 15 mm including the case.
Does the ROCKBROS work on a step-through trike?
Only with a frame tube to strap to.
Are these waterproof?
Only the ROCKBROS pouch has sealed zippers.
Bottom Line
The Kinizuxi is the best all-round pick at this budget. Choose the MCOTOP for the largest phones or the ROCKBROS for a waterproof pouch.
