Magnum — FAQ
Does AMPERBIKE sell Magnum bikes directly?
No. AMPERBIKE is a catalog and comparison index for Magnum and other US-available ebike brands. When you find the Magnum model you want, the "View on Magnum.com →" button takes you direct to the brand's site to complete your purchase — pricing, warranty, shipping and returns all go through Magnum.
Why use AMPERBIKE if I can go straight to Magnum.com?
Because comparison across brands matters. Magnum only sells Magnum. AMPERBIKE indexes Magnum, Engwe, Lectric, Aventon, Lankeleisi, Himiway and 30+ more — so you can spec-compare a Magnum model against any other ebike before you buy. We also surface fitment-checked parts and upgrades for Magnum models once you've bought.
How is the Magnum catalog kept current?
We pull Magnum's public product feed automatically. New models appear in our index typically within 24-48 hours of being listed on Magnum.com. Discontinued models are flagged but kept indexed so older bike owners can still find compatible parts.
What if a Magnum model isn't listed on AMPERBIKE?
Email info@amperbike.com with the model. If it's listed on Magnum's public site, we'll add it to our index. Some discontinued or region-exclusive bikes may not have public feeds — for those we recommend checking Magnum.com directly.
