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