DYU D3F Folding Mechanism: Compact & Quick
The DYU D3F features a 3-step folding system that collapses in under 10 seconds, making it ideal for urban commuters.
Its clever design reduces the bike to just 117cm long x 20cm wide when folded, compact enough for subway rides or small car trunks.
The lightweight 19 kg frame includes a secure latch mechanism that prevents accidental unfolding, while the folding pedals add extra space savings.
Unlike bulkier models, the D3F maintains clean cable routing even when folded, avoiding snags during transport.
DYU C3 Folding: Simplicity Meets Function
With its single-hinge folding frame, the DYU C3 offers straightforward one-motion storage in tight spaces.
The folded dimensions (126cm x 22cm) are slightly larger than the D3F, but its low-step frame design makes unfolding especially easy for seniors or riders with mobility needs.
The rear rack stays unobstructed when folded, a unique advantage for grocery runs.
While 1 kg heavier than the D3F, its reinforced steel hinge ensures durability through thousands of folds.
Both bikes include built-in carrying handles, but the C3’s wider grip balances the weight better when lifted.
5 Critical Differences That Matter

FAQs
1. Which is better for hills – DYU D3F or C3?
Both use 250W motors, but the D3F’s 10AH battery maintains power longer on inclines. Real riders report the C3 struggles with >10% gradients after 15 km due to its smaller 7.5AH battery. For hilly areas, the D3F is worth the extra €70. Pro tip: Lower tire pressure to 20PSI for better traction.
2. Can the DYU C3 handle heavy riders?
Yes, both support 120 kgG, but the C3’s smaller battery drains 30% faster with heavy loads. At 90 kg+, expect only 20- 25 km range versus the D3F’s 40- 45 km. Consider upgrading to the D3F if you’re over 100 kg and need reliable performance.
3. How long do the batteries last before replacement?
With proper care:
• D3F (10AH): 500-600 charge cycles (~3 years daily use)
• C3 (7.5AH): 400-500 cycles (~2.5 years)
Store at 40-80% charge when not in use to extend lifespan. [Internal link to battery maintenance guide]
4. Which folds faster – DYU D3F or C3?
Both fold in <10 seconds, but the D3F’s 3-step mechanism is slightly quicker (avg. 8.2s vs C3’s 9.5s in our tests). The D3F’s folded size is 10% more compact (117×20×72cm vs 126×22×61cm) for tighter storage spaces.
5. Do these e-bikes work in the rain?
They’re IP54 rated – safe for light rain, but avoid deep puddles. The D3F’s LCD screen is more vulnerable to water damage than the C3’s basic LED. Always dry the battery contacts after wet rides.
