Cube Nulane Hybrid review & modifications

Introduction

For years I was looking for a lightweight gravel e-bike with a mid-drive motor as the base for my Maxun One solarbike.  But suitable models were not available on the market. That only changed when Cube released the Nulane Hybrid C:62 SLX 400X. This bike weighs just 14 kg.

In my opinion, this is one of the best gravel e-bikes on the market. At €4200 the price is also quite reasonable, since other e-bikes with this low weight and level of finish are more expensive at other brands. I don’t understand why e-bikes are still being sold for the same price that weigh more than 20 kg.

Implemented Improvements

Personally, I find the handlebar of the Cube Nulane Hybrid uncomfortable because it is too low and too straight. In this article I describe how I replaced the handlebar and how I further modified the bike.

Alternative e-bikes

There is also a cheaper version: the Cube Nulane Hybrid C:62 Race 400X. This one costs €3200. The main difference is that it does not have electronic shifting.
Here are some comparable mid-drive e-bikes:

  • Scott Solace Gravel eRIDE 30 (motor TQ HPR50) — 13.5 kg — €6000
  • Stevens E-Getaway (motor TQ-HPR60) — 13.2 kg — €6100
  • Rose Backroad Plus (motor Shimano EP8) — 15.6 kg — €3600

Lightweight carbon rear rack upgrade

I equipped the Cube e-bike with a self-built lightweight carbon rear rack weighing only 300 grams. I plan to produce this; let me know if you are interested. See my article: Lightweight carbon rear rack for sport bicycles.

Ergotec Riser Bar 50 Comfort handlebar upgrade

I replaced the handlebar with an Ergotec Riser Bar 50 Comfort / 31.8 handlebar. This handlebar is more comfortable and has a rise of 5 cm and an angle of 25°. I shortened the handlebar by 4 cm on each side.

Shockstop suspension stem installation for improved comfort

To raise the handlebar further, I used the Shockstop +30 deg x 100 mm stem.

You get two benefits at once: effective handlebar suspension and a higher handlebar position. The top plastic ring of the Cube needs to be modified; this works best with a Dremel tool.

Saddle

I replaced the original Cube saddle with my favorite saddle: Selle Royal Mach. This saddle is from the brand Selle Royal, but it is only available at Decathlon.
