Atala Extrafolding 5.6 vs 6.6: Compare the 2026 Systems
Atala Extrafolding 5.6 and 6.6 share a 20-inch fat-tyre folding format, but the 2026 catalogue describes different electrical and braking systems. The 5.6 is the 36 V entry and the 6.6 the 48 V entry. Their common silhouette should not turn into an assumption that batteries, displays or brake parts can be exchanged.
Atala Extrafolding: read the battery and system identities
The 5.6 page lists a 474 Wh, 36 V battery behind the seat tube, with Smart BMS UART. Its A220 LCD colour display is also described as UART. The 6.6 page specifies a Phylion 627 Wh, 48 V battery in that location with Smart BMS CAN, and an A220 CAN display.
Both motor entries name Ananda rear-hub assistance and 55 Nm maximum torque. The catalogue separates 250 W nominal output from maximum figures of 400 W and 555 W respectively. These printed categories should remain distinct; they do not establish measured acceleration, a legal classification in every market or permission to alter settings.
Mechanical and hydraulic discs distinguish the builds
The 5.6 lists mechanical dual-synchronous disc brakes, while the 6.6 lists hydraulic discs. Both pages name 160 mm rotors with brake-lever switches. Their seven-speed transmissions use 46-tooth chainrings and fourteen-to-twenty-eight rear ranges, with folding pedals and 20 × 4.00 Fat Trail tyres.
This is a complete-build comparison, not a brake-conversion proposal. The same wheel or rotor diameter cannot supply the requirements for replacing controls, hydraulic parts or electrical switches. A mechanic should identify the installed systems before assessing any change.
Storage figures belong to these exact catalogue entries
The notes give an open length of 171 cm and a folded package of 101 cm long, 76 cm high and 45 cm wide for both. Those dimensions help assess a space on paper; they do not verify lifting weight or acceptance by a transport operator. Check the actual bicycle and any attached accessories before relying on the package measurement.
The catalogue lists 620 mm handlebars, while the inspected live pages say 580 mm. The live 5.6 display row says CAN despite the catalogue's UART wording. Keep those discrepancies visible. Browse the Atala model collection or the range background without combining different equipment records into one specification.
FAQ
Which 2026 entry is 48 V?
Extrafolding 6.6 is the 48 V, 627 Wh entry; 5.6 is listed as 36 V, 474 Wh.
Are the listed brakes the same type?
No. The selected 5.6 lists mechanical discs and 6.6 hydraulic discs.
Does a shared folding frame approve a battery swap?
No. Voltage, system communication and the complete approved electrical assembly must be matched separately.
