Adlar Hybrid SRAM Rival XPLR AXS E1 1x13sp + TQ HPR50

The available builds center on three main configurations: a SRAM Rival XPLR AXS E1 1x13-speed model, a Shimano GRX 1x12-speed model, and a Flat Bar Shimano XT 1x12 model, all paired with the TQ HPR50 system. The reviewed 2024 GRX builds are listed around £6,078 for the standard bike and £6,599 with the e-bike system and bikepacking kit, while Opticycles also lists US pricing of $8,469 for the flat-bar XT build and $9,066 for a GRX bikepacking-equipped version. Across the Shimano builds, the drivetrain theme is consistent: 1x12 gearing with a 38T chainring and 10-51 cassette, plus Shimano hydraulic disc brakes and 700c aluminum wheels.

The spec differences are less about frame performance than rider intent. The GRX 800/600 drop-bar builds are the more conventional gravel option, better suited to longer paved links and varied hand positions, while the XT flat-bar version emphasizes steering leverage and technical control. Bikepacking-kit versions add a clear use-case advantage for riders intending to tour or ride loaded. One notable through-line is that these are premium-priced builds using dependable, gravel-appropriate parts rather than flashy wheel upgrades; reviewers specifically noted the use of aluminum rims at a price point where some buyers may expect more.

Reviewers are notably consistent about the Adlar Hybrid's ride character: the TQ HPR50 system gives the bike a very natural, unobtrusive feel, with several describing it as more like a "turbocharged gravel bike" than a typical e-bike. On smoother gravel and pavement, it is repeatedly praised for road-like handling and a light-feeling assist that does not overwhelm the rider's pedal stroke. The 47 mm tires also drew frequent mention, with reviewers crediting them for smoothing rough tracks and bridleways without making the bike feel vague or mushy. Whether in flat-bar XT trim or drop-bar GRX versions, the bike is generally seen as composed, planted, and unusually agile for an e-gravel model.

The criticisms are just as consistent. Multiple reviewers note that the 50 Nm motor trades stealth and refinement for limited punch on steep, sustained climbs, especially with bikepacking loads. The 360 Wh battery is considered adequate for long mixed-terrain rides if assist is managed carefully, but not generous enough to remove range concerns on bigger all-day or multi-day outings. Value is another recurring weak point: Opticycles' listed OptiScores range from 5.8 to 6.4 out of 10, reflecting a view that the bike delivers a high-end experience but not class-leading price-to-spec value. Reviewers also point out practical trade-offs between cockpits, with the flat bar improving steering precision in technical terrain while sacrificing the multiple hand positions and cruising efficiency of the drop-bar builds.
