Mahle M40 Review: The First Real Avinox Challenger?

The Mahle M40 is one of the most talked-about new eMTB motors of 2026, and after months of testing it on my custom SB Projects Dream Build, it's finally time for a full review. In this video, I take a deep dive into the Mahle M40 motor, covering everything from power delivery, ride feel, range, battery options, tuning, the Mahle app, sound levels, Auto Hold, Traction Control, Dynamic Overrun, and how it compares against Bosch, Specialized, Shimano, Giant, and DJI Avinox.

The M40 delivers an impressive 105Nm of torque and 850W peak power while maintaining one of the most natural ride feels I've experienced on an electric mountain bike. But is it enough to compete with the current market leaders? Let me know in the comments what you think of the Mahle M40 and which motor system you'd choose for your next eMTB. 👇 Chapters 00:00 Introduction & Trail Action 00:46 SB Projects Dream Build Bike Check 01:52 Mahle M40 Specs & System Overview 02:49 Topeak Sponsor Segment 03:46 Who Is Mahle? 04:31 Motor Appearance & Integration 04:57 How Does The Mahle M40 Ride? 06:05 Auto Hold Explained 06:40 Traction Control Explained 07:14 Dynamic Overrun Feature 08:46 Mahle App Overview 09:16 Motor Mapping & Custom Tuning 09:57 Sound Test (No Noise Reduction) 11:13 Riding Above The Limiter 11:33 Battery Options & Real-World Range 12:15 Mahle M40 vs Bosch, Specialized, Shimano & Avinox 12:46 What I Don't Like About The M40 14:12 Final Verdict & Conclusion Bike Build Featured In This Video Mahle Prototype Carbon Frame Mahle M40 Motor 800Wh Battery Fox 38 Fork Fox Float X2 Shock Industry Nine Hubs We Are One Fuse Carbon Rims Shimano XTR Drivetrain Shimano XTR Brakes Galfer Rotors Fox Neo Wireless Dropper Ergon Saddle OneUp Bars Schwalbe Magic Mary Tyres Key Topics Covered ✅ Mahle M40 Review ✅ Mahle M40 vs Bosch CX Gen 5 ✅ Mahle M40 vs DJI Avinox ✅ Mahle M40 vs Specialized 3.1 ✅ Mahle M40 Range Test ✅ Mahle M40 Sound Test ✅ Mahle App Setup & Tuning ✅ Auto Hold & Traction Control ✅ Best eMTB Motors 2026 ✅ Full Power Electric Mountain Bikes ✅ eMTB Reviews & Testing Follow Sam's Bikes For honest eMTB reviews, dream builds, motor comparisons, range tests and trail riding videos, make sure you're subscribed and hit the notification bell. #MahleM40 #eMTB #ElectricMountainBike #EMTBReview #Mahle #MahleEMTB #BestEMTB #EMTBMotor #BoschCX #SpecializedEMTB #DJIAvinox #MountainBiking #SamsBikes #EMTB2026 #TrailBike #EnduroBike #EBikeReview #BikeReview #EMTBLife #FoxSuspension
