Spesh have had a few quality and design problems with the 2019 Levos.
The early motors were very loud; Replaced under warranty.
Dirt ingress due to poor design; new motor covers, a sponge, and now a deflector shield. It is still unclear if all dealers are fitting these parts under warranty or if the new bikes are coming fitted with them.
Motor power cable; it’s a generic Brose part and due to the length has a tight 180degree bend close to the connector which causes cracking and shorting issues. There is supposedly a new cable, but Spesh seem reluctant to admit there is a fault.
On the eMTB forum there are quite a few people who’ve suffered motor or battery failures, along with the design issues. The warranty problems are easily sorted but the design issues seem to be a lottery as to whether you’ll get an easy fix or a battle with your dealer.
Bosch and Shimano motored bikes aren’t much better. The Bosch has a well known design flaw that the Gen 4 motor has eliminated and the Shimano seems to have an issue with the bottom bracket bearings if ridden hard.
I’m on my third Bosch motor in under 1500 miles and I know people with Spesh and Shimano bikes who’ve had motors and/or batteries fail.
EDIT: Spesh are also experiencing issues with the TCU on the 2019 bikes.
