E-biking in Valtellina isn't just a less strenuous way of getting uphill, but an instrument for improving access to the mountain, even on technical terrain.
With a full e-mtb you can take on long tours or explore moderate single tracks through forests and pastures. There's so much choice for all levels, but make sure to plan accordingly, respect other trail users and keep an eye on your battery level. If you like long-distance rides then check out the Sentiero Valtellina between Lake Como and Bormio, a 100 km route mainly made up of cycle paths, also suited to gravel and trekking e-bikes.
