Our verdict
Makes sense for riders who already know their size and want a 21-speed hybrid with front and rear disc brakes at $359.99. Look elsewhere if you need a stated rider height, a brake type or a fuller description, none of which the page gives. The main caveat is a thin page: every figure is the store's own and the table omits rider height.

Why 3.1/5: Held back by a page with no full specification table, store pages that disagree on their own terms, thin outside information about the store and no independent test of this model.
A short page describes the Zukka Seagull, a 700x32C hybrid and road bike that Hycline sells under the Zukka name at $359.99. It lists Shimano's 21-speed (3x7 gears) system, front and rear disc brakes with a 160 mm rotor, WANDA tires, an aluminum alloy frame and a weight of 29.10 lb, but it gives no rider height and no descriptive paragraph.

Options and pricing
The Seagull comes in Blue, Black or Grey at one price, $359.99, in the single size option 700x32C, and all three variants were in stock when read. No crossed-out price is shown. The page says the bike is 85% pre-assembled and that installation tools and pedals are included.
How it compares
The Zukka Slash 700C Hybrid Bike shares the 700x32C tire size and costs $319.99, with a listed 33.73 lb against this bike's 29.10 lb. The Dorace SLR 700C Road Bike is $339.99 with 700x28C tires and 28.89 lb. The Ecarpat Druk 700C Road Bike is $319.99 with 700x28C tires and 28.89 lb.
Shipping, returns and warranty
Shipping: the shipping policy covers the continental US only and says the store does not ship outside the United States (the About page mentions DHL and USPS for orders outside the US), yet its table lists a Hawaii and Alaska rate of $25.99 under a heading that excludes both. General-size items ship free over $99.99 (Standard, 4 to 6 days) or for $5.99 below that, with Expedited at $7.99 and 3rd Day at $12.99; bikes and suspension forks count as oversized and ship Standard in 7 to 15 days for $29.99, so a bike's free-shipping banner does not remove that charge. Orders leave within 1 business day with a tracking number, delivery needs a signature, and damage must be noted on the delivery receipt and reported within 24 hours with photos and video; product pages say the order comes from the nearest of 7 US warehouses, and the About page gives a Stockton, California address. Returns: the refund policy gives 30 days for new, unused items in original packaging, with photos sent first to get a return label; for a change of mind the buyer pays return shipping (the About page calls 30-day returns free), while a defective item can be returned within 30 days without restocking or return fees, and after that the policy offers help with manufacturer warranty support. The refund is processed within 48 hours of approval in the policy and within 24 working hours of the warehouse receiving the item in the FAQ. Warranty: the Terms of Service hold only an as-is disclaimer and are governed by the laws of China; the one-year figure comes from the product pages (a 'Manufacturer Warranty' row on most bike pages and a '1-year warranty' line under the buy box), and no page says what it covers or how to claim.
Before you buy
The page shows no customer reviews of this bike; the store's own review page lists 3,669 reviews, and 23 of the 25 it displays are about tires or tubes. Reputation: on Trustpilot (read on the Australian site) hyclinebike.com is an unclaimed profile with one review, five stars from April 2023 about 700c tires, and nothing newer. The store's review page shows 4.66 stars from 3,669 reviews through a Judge.me widget that we could not verify. The registry shows hyclinebike.com registered on 2 November 2022, while the About page says the site opened in 2019 and the company grew from a repair shop and a tire factory; it gives a Stockton, California address, and the Terms are governed by the laws of China. Web searches on 22 October 2026 found no independent review of the store's complete bikes. The review shows the code FACESTORE. A cart test on 22 October 2026, made without the affiliate link, took 5% off bikes, a trike and parts; if the discount line is missing from your cart, enter FACESTORE at checkout.
What we liked
- Front and rear disc brakes, with a 160 mm rotor size given in the table
- Shimano's 21-speed (3x7 gears) system named by the page, matching the table's 21-speed entry
- An aluminum alloy frame at a table weight of 29.10 lb
- The page names its tire maker, WANDA
Worth noting
- The page gives no rider height and no description of who the bike fits
- No brake type (mechanical or hydraulic) is stated, only a rotor size
- There is no descriptive paragraph, so little detail exists beyond a short feature list
Questions before you buy
What rider height does the Zukka Seagull list?
The page does not say. Its table gives a frame size of 21 in. but no rider height range, so the fit has to be confirmed with the store.
What does the Seagull's gearing entry say?
The page names Shimano's 21-speed (3x7 gears) change system and the table lists 21-speed / Hybrid. It gives no shifter or derailleur model.
What brake details does the Seagull page give?
The page lists front and rear disc brakes and the table gives a rotor size of 160 mm/6.29 in. It does not say whether they are mechanical or hydraulic.
Where does Hycline ship, and what does a bike cost to ship?
The policy covers the continental US only (Hawaii and Alaska are listed at $25.99 in one table but excluded in its heading). Bikes and suspension forks are oversized: Standard shipping takes 7 to 15 days after handling and costs $29.99, even though the page banner offers free shipping over $99. Orders ship within 1 business day with tracking and a signature at delivery.
What is the return window?
30 days for new, unused items in original packaging, after sending photos and receiving a return label. You pay return shipping for a change of mind (the About page calls returns free); a defective item has no restocking or return fee. This page's spec table says 'Returnable 90-Day', which the policy does not repeat.
Does the bike have a warranty?
Most bike pages list a 1-year manufacturer warranty, and the buy-box blurb says '1-year warranty', but the Terms of Service and the policies name no warranty period, coverage or claim process. Ask [email protected] for the terms in writing before ordering.

What we couldn’t verify
- The page gives no rider height and no descriptive paragraph, so the intended rider size and use are not stated.
- No brake type or brake brand is given, only a 160 mm rotor size; the page claims double brakes give faster braking without any source.
- The 21-speed claim is credited to Shimano with no model, and the page gives no source for the 29.10 lb weight.
- The return policy gives 30 days, while this page's table says 'Returnable 90-Day' and the About page calls 30-day returns free; the policy makes buyers pay return shipping for a change of mind.
- The store's terms and policies name no warranty period or coverage; the 1-year figure appears only on product pages.
- The shipping policy treats bikes as oversized at a flat $29.99 (Standard, 7 to 15 days) while the buy-box blurb says free shipping over $99; the policy also lists a Hawaii and Alaska rate while excluding both.
- No independent test or customer review of this model was found in web searches made on 22 October 2026, and the page's own copy is the only source for its figures.
