84. ARE MID DRIVES STABLE FOR TADPOLE TRIKES? • How and Who will answer that question? • Why mid-drives have been made popular for mountain bikes? • Same rules don’t apply in the Trike World?
85. MID-DRIVES BLIND LEADING THE BLIND Why Mid-Drives will not last in the bicycle industry?
86. MID-DRIVE ISSUES • Expensive; • Highly Complex; • High Maintenance Cost; • Unreliable; • Limited Lifetime.
87. THE BATTLE Mid Drives Direct Drives The Secret Weapon
88. WHY MID-DRIVES BECAME A SOLUTION? 2011 Mid-Drives produced 30Nm of Torque Panasonic Daum Etc. No Issues with Existing Bicycle Components 40 to 90 Nm Journey 2018 Re-Engineered of Bicycle Components Commitment to a Wrong Solution Continues Expensive, Wasteful and Unreliable DemiseofBionXandGoSwissDrive Industry Wide Commitment to Mid-Drives Continues 2021 BeginningofDeclineofMid-Drives
