Reason 2027

The Megamo Reason 2027 is a Spanish carbon enduro eMTB built around the DJI Avinox M2S motor and an 800 Wh integrated battery, with 160 mm of travel front and rear in a full 29er package. Headline numbers: 22.04 kg claimed, 150 Nm of peak Avinox torque, a properly slack 63.5 degree head angle and reach progressing from 442 mm on S to 512 mm on the new-for-2027 XL. The community framing is enthusiastic: @Rob Rides EMTB describes it as "a rocket on my first ride" and ranks it alongside the Forbidden Druid and Unno Mith as one of the best-designed Avinox eMTBs at launch.

Drive system and range. The Avinox M2S delivers 150 Nm of peak boost torque (130 Nm continuous), a manufacturer-claimed 1500 W peak (1300 W continuous) and weighs just 2.63 kg. The 800 Wh DJI Avinox battery is fully integrated and not removable. @COOLBIKE documents that battery removal on the Reason requires removing the motor itself, similar to the Crussis e-Full. @biasbilt flags water-ingress reports on the Avinox thumb switches across both the Amflow and Megamo Reason: worth knowing about in wet conditions.

Geometry and handling. A 63.5 degree head angle is properly slack and modern-enduro, slacker than most rivals at this travel. Reach steps 442 mm on S, 470 mm on M, 500 mm on L and 512 mm on the new 2027 XL. Chainstays grow with size from 450 mm on S through 453/454 mm on M, 458 mm on L and XL: a genuine size-tuned approach that helps tall riders find balance. Wheelbases run 1233 to 1334 mm. A flip-chip adds approximately 0.2 degrees of angle and 3 mm of BB-height variation. @Rob Rides EMTB flags that the stock 35 mm stem feels twitchy (50 mm recommended), the 20 mm bar rise is short for larger sizes, and the L can feel more like an XL on geometry comparison.

Build and value. Seven trims. The base at £5999 (also CRB 07) with Fox 36 Float AWL HD fork and Float Rhythm shock, Shimano XT M8220 four-piston brakes and full XT M8100 1x12 drivetrain. CRB 05 at £6999 with Fox 38 Performance. CRB 03 at £7999 with Fox 38 Factory and SRAM Eagle 90 T-Type. CRB 03 AXS at £8499 swaps in SRAM AXS Transmission electronics. CRB 02 at £8999 brings RockShox ZEB Ultimate, Vivid Ultimate shock, SRAM Maven Ultimate brakes with Galfer Shark rotors. Top of the line is CRB 01 at £10999, 22 kg, with Fox Factory 38 and Float X2 and SRAM XX Eagle AXS T-Type. Value pick is CRB 05 at £6999: Fox 38 and the same chassis as the £10999 top trim.

Community-verified strengths. Three things owners praise. @Toomanybikesnotenoughlegs reports the 160 mm chassis suits everything from single track to Lake District trails and bike parks without ever feeling under-suspended. The Avinox M2S brings game-changing power-to-weight: 22 kg with a 150 Nm motor is exceptional. @Rob Rides EMTB's on-trail "rocket" verdict and the dealer expansion (with three Megamo dealers within a 90 minute drive of one Scottish base) is a positive signal.

Caveats and known gripes. Three flags. @Rob Rides EMTB documents detailed cons: stock EXO casing tyres too light, twitchy 35 mm stem, headset cable routing on alloy versions creating maintenance overhead (carbon versions use normal routing per @COOLBIKE), non-removable battery, mild flip-chip change, short 20 mm bar rise for larger sizes and a Large sizing closer to an XL. @simonali19 reports the bike weighs notably more than a comparable analogue FS (~10 kg reference), making vehicle loading awkward. And @biasbilt's water-ingress flag on Avinox thumb switches is a live concern.

Verdict. The Megamo Reason 2027 is the bike for the rider who wants the most polished carbon Avinox M2S enduro chassis below the Amflow, with proper modern geometry, size-tuned chainstays and a strong trim ladder. If you want a removable battery, the absolute deepest dealer network or proven multi-year warranty data, look at a Specialized Levo Gen 4 or Cannondale Moterra LT. Production status is current.
