Deity Highside 80mm Rise Bars transform the riding experience on eBikes and mountain bikes by offering exceptional height, width, and ergonomics. After extensive testing on gravel roads and backroad adventures, these high-rise handlebars have earned the highest rating possible. This comprehensive review breaks down every aspect of performance, fit, and value.
Rating Breakdown
Setup & Fit earns 5/5 because the 800mm width is absolutely perfect for my wingspan and required zero trimming—bolt on, center it, ride.
Comfort & Control gets 5/5 thanks to the 80mm rise paired with a 9° backsweep / 5° upsweep that keeps me a little more upright and feels natural on the wrists while staying precise when things get rough.
Ride Feel scores 5/5 because these bars feel super comfortable on long backroads, but still give that wide-bar leverage and confidence when the surface turns loose, washboard, or chunky.
Build & Aesthetics earns 5/5 with Deity’s gradient butting, bead-blast finish, and overall “purpose-built” vibe that looks right at home on an adventure fat-tire rig.
Availability & Value rates 4/5: MSRP is solid at $84.99, but specific color/graphic options can be in/out of stock depending on timing.
Deity Highside 80mm Rise Bars – 5/5 Trail King
The Deity Highside 80mm rise bars are, for me, the definition of “done searching.” The rise is absolutely perfect—just enough to keep me more upright for adventure riding without making the front end feel vague or disconnected. The sweep numbers (9° back / 5° up) hit that comfortable, neutral hand position that makes long days feel easier on the upper body.
Setup and Fit
- The 35/OS version comes in at 800mm wide, and that width was perfect for me—no trimming required.
- The 35mm clamp matches modern stems and gives the bar a stout, confidence-inspiring feel.
- Once installed, there’s nothing fussy here—just a cockpit position that feels immediately “right.”
On-Road / Backroad Performance
- The big win is posture: the 80mm rise keeps me comfortably more upright, which helps on long, bumpy miles.
- Control stays excellent—wide leverage for steering authority, with a bend that doesn’t twist your wrists into a weird angle.
- When the road turns to washboard or loose gravel, these bars help keep the front end calm and predictable instead of feeling twitchy.
Build, Finish, and Confidence
- Deity uses gradient butting and a full bead blast finish aimed at durability and fatigue resistance.
- Claimed weight for the 80mm rise is 375g, which is reasonable for a big-rise, big-width bar built for hard use.
- Covered by Deity’s lifetime crash replacement policy for the original owner.

Rating
For adventure-focused riding where comfort and control matter more than being slammed low and aggressive, the Deity Highside 80mm rise bars earn a perfect 5/5 “Trail King” rating from FTN.
Bottom Line
If you want a cockpit that feels instantly comfortable, keeps you a little more upright for long days, and still maintains excellent control when the backroads get rough, the Highside 80mm is an easy recommendation. These are the bars I’d buy again without hesitation. The fit is so perfect on the Nomad, I put them on the Vagabond too!
