What we like, and what to watch
What we like
- Compact, low-weight options. The range includes a 14-inch D3S folder listed at about 19 kg and the SP1 listed at 14 kg without battery, alongside larger fat-tire models.
- EU warehouses. The shipping policy says orders ship from Poland or Germany within 2 working days, with free shipping over €100.
- Published return window. Returns can be requested within 30 days of delivery, and defective items within 30 days can be returned or exchanged.
Watch out for
- Change-of-mind e-bike returns cost €200 per bike (€100 per battery), and the bike must show under 10 km.
- The warranty page says 1 year (prorated for batteries), while product pages say 12-24 months; confirm the terms before buying.
- Delivery estimates differ across the shipping page, FAQ and banner (2-3, 3-5 and 5-7 days), and Germany is not on the shipping policy's country list.
- Range figures are inconsistent on some pages (the M20 lists both 100 miles and 160 km), and all specs are the brand's own claims.
Who should buy from DYU
DYU makes sense if you live in the EU and want an affordable 250W folding, city or fat-tire e-bike shipped from a European warehouse. If you want a clearly stated multi-year warranty or free change-of-mind returns, look elsewhere.
DYU
Riders in the EU who want a budget 250W folding, city or fat-tire e-bike capped at 25 km/h, shipped from a European warehouse with a published 30-day return window.
