The Ultimate Giant Store Onomichi Bike Rental Prices Guide: Cycle the Shimanami Kaido in Style

Onomichi is a town where time seems to slow down, caught between the steep, temple-lined hills and the shimmering blue of the Seto Inland Sea. For many travelers, this nostalgic port city in Hiroshima Prefecture serves as the starting block for the world-renowned Shimanami Kaido—a 70-kilometer cycling route that traverses six islands and spectacular suspension bridges. While there are several ways to tackle this journey, renting a high-performance bicycle from the **Giant Store Onomichi** is widely considered the gold standard for enthusiasts and comfort-seekers alike.

Located within the chic, industrial-cool confines of Onomichi U2—a converted seaside warehouse—the Giant Store offers more than just a bike; it provides a gateway to a seamless Setouchi adventure. Whether you are an experienced cyclist aiming to conquer the route in a few hours or a casual traveler looking to enjoy an e-bike breeze to the nearest island, understanding the rental structure is key to planning your 2026 trip. This guide breaks down everything you need to know about Giant Store Onomichi bike rental prices, booking procedures, and local tips to ensure your ride across the sea is nothing short of legendary.

1. Why Choose Giant Store Onomichi for Your Shimanami Kaido Adventure?

When planning a Shimanami Kaido trip, you will encounter two main rental options: the public “Shimanami Rental Bike” system and the premium “Giant Store” service. While the public system is budget-friendly, the Giant Store Onomichi caters to those who prioritize performance, comfort, and reliability.

The primary advantage of renting from Giant is the **quality of the fleet**. Unlike the heavy, often well-worn bikes found in public sheds, Giant provides professionally maintained road bikes, hybrid “cross” bikes, and state-of-the-art E-bikes. These machines are significantly lighter, making the climbs up to the bridges much more manageable.

Furthermore, the location in **Onomichi U2** adds a layer of convenience. You can stay overnight at the bicycle-themed Hotel Cycle, grab a gourmet breakfast at the Yard Cafe, and walk ten feet to pick up your rental. The shop staff are experts who ensure your saddle height is perfect and your gear is tuned before you hit the “Blue Line”—the navigation stripe that marks the route all the way to Imabari.

2. Giant Store Onomichi Bike Rental Prices: A Detailed Breakdown

As we look toward the 2026 cycling season, pricing at the Giant Store remains structured around the type of bicycle and the duration of your rental. It is important to note that Giant operates on a calendar-day basis, not a 24-hour clock.

**Carbon Fiber Road Bikes (Performance)**

For those looking to fly across the bridges, the high-end carbon road bikes (like the TCR or Defy series) are the top choice.

**1-Day Rental:** Approximately ¥7,700 – ¥15,000 (depending on the specific model and component level).

**Additional Days:** Usually discounted by about 20-30% for subsequent days.

**Aluminum Road Bikes (Standard)**

A great middle-ground for fitness enthusiasts who want speed without the premium price tag of carbon.

**1-Day Rental:** Approximately ¥5,500 – ¥7,000.

**Cross Bikes / Hybrid Bikes**

Ideal for casual riders who prefer an upright position and comfort over pure speed. These are the most popular choices for families and leisurely island hoppers.

**1-Day Rental:** Approximately ¥4,400.

**E-Bikes (Power-Assist)**

E-bikes have revolutionized the Shimanami Kaido. They flatten the hills leading up to the bridges, making the 70km trek accessible to almost anyone. Giant’s “Road E+” and “Escape RX-E” models are highly sought after.

**1-Day Rental:** Approximately ¥7,700.

*Note: E-bikes often have limited availability for one-way rentals due to charging logistics.*

**Kids’ Bikes**

Giant provides high-quality youth bikes to ensure the little ones aren’t struggling with heavy frames.

**1-Day Rental:** Approximately ¥3,300.

**Mandatory Insurance:** A small insurance fee (usually around ¥500–¥1,000) is often required to cover basic damage to the bike, though it usually does not cover theft or total loss. Always verify the current terms at the counter.

3. The One-Way Rental System and Drop-off Fees

One of the most common questions for travelers is: *”Do I have to ride back to Onomichi?”* While the round trip is a beautiful 140km, most travelers prefer a one-way journey from Onomichi to Imabari (Ehime Prefecture).

Giant Store offers a **One-Way Drop-off Service**, allowing you to return your bike to the Giant Store Imabari (located at Imabari Station). However, this service comes with specific conditions:

1. **Advance Reservation:** One-way rentals must be booked in advance.

2. **One-Way Fee:** There is a surcharge for this service, typically around **¥3,300 per bike**.

3. **Bike Limitations:** High-end carbon road bikes may occasionally be restricted from one-way rentals depending on fleet availability, so always check the booking portal for “One-way” compatibility.

If you are on a budget, you can drop the bike off in Imabari and take the Shimanami Cycle Express bus or a ferry back to Onomichi.

4. How to Book: Reservations and Availability

The Shimanami Kaido is no longer a “hidden gem”—it is a bucket-list destination. Consequently, Giant Store Onomichi rentals can book up weeks in advance, especially during the peak seasons of April-May (Cherry Blossoms) and October-November (Autumn Leaves).

**Booking Window:** Reservations typically open **60 days in advance**.

**Online Portal:** Giant uses a dedicated Japanese/English booking system on their website. You will need to select “Onomichi” as your pick-up location and specify your height to ensure the correct frame size.

**Walk-ins:** While walk-ins are technically possible, they are highly discouraged. If you show up without a booking during a weekend or holiday, you will likely find the store completely out of stock.

**Cancellation Policy:** Usually, cancellations made a few days in advance incur no fee, but “no-shows” will be charged. Given the unpredictable coastal weather, keep an eye on the forecast, but remember that the bridges are generally safe to cycle even in light rain.

5. Essential Gear and Local Logistics

When you rent from Giant, the price includes more than just the frame and wheels. Here is what is typically included and what you should bring yourself:

**Included with Rental:**

**Helmet:** Safety is paramount, and helmets are included in the rental price.

**Basic Lock:** A sturdy cable lock is provided.

**Puncture Repair Kit:** Most rentals come with a spare tube and a small pump, though the staff expects you to have basic knowledge of how to change a tire if you are heading deep into the islands.

**Luggage Forwarding (Takkyubin):**

Riding 70km with a 15kg suitcase is not recommended. If you are staying at Onomichi U2, they can help arrange **Sagawa or Yamato Transport** to send your luggage to your hotel in Imabari or your next destination (e.g., Hiroshima or Osaka). There is also a local service called “Shimanami Cycle Carry Service” that provides same-day delivery between specific hotels along the route for a reasonable fee.

**What to Bring:**

**Padded Cycling Shorts:** Even on a premium Giant saddle, 70km is a long time for your sit-bones.

**Gloves:** To prevent blisters and protect your hands from the sun.

**Water Bottle:** The bikes come with bottle cages. You can refill at “Cycle Oasis” stations (cafes, shops, and gas stations) across the islands.

6. Navigating Onomichi: Cultural Highlights Before You Pedals

Before you speed off toward the bridges, take at least half a day to explore Onomichi itself. This city is famous for its **Temple Walk**, a path that connects 25 different temples along the hillside.

**Senko-ji Temple:** Accessible via a ropeway, this temple offers the most iconic view of the Onomichi Channel. The contrast of the orange temple structures against the blue sea is breathtaking.

**The Path of Cats (Neko no Hosomichi):** A narrow, whimsical alleyway decorated with “fukuishi-neko” (lucky stone cats) and home to many real feline residents. It’s a photographer’s paradise.

**Onomichi Ramen:** You cannot leave without trying the local delicacy. Characterized by a soy-sauce base with flat noodles and back fat (seabura), it is the perfect “carb-load” before a long ride. **Tsutaya** and **Shu-u-ken** are local favorites, but be prepared to wait in line.

FAQ: Frequently Asked Questions

Q1: Can I rent a bike for just a few hours to visit the first island?

Yes, but you will still pay the full 1-day rental rate. For a quick 2-hour trip to Mukaishima (the first island), the public rental system might be more cost-effective. However, for anything longer than 3 hours, the comfort of a Giant bike is worth the extra cost.

Q2: What happens if the bike breaks down mid-way?

Giant bikes are high-quality and rarely fail. However, if you have a mechanical issue, you should contact the store. Giant does not typically offer “roadside rescue” on the islands. Most riders use the “Shimanami Island Shield” (a local bicycle insurance/aid service) or seek help at a “Cycle Oasis.”

Q3: Is the route difficult for non-cyclists?

The Shimanami Kaido is designed for everyone. While there are some inclines (the ramps leading up to the bridges are usually a 3% grade), they are gradual. If you are worried about fitness, **rent an E-bike** from Giant Store Onomichi; it makes the hills feel like flat ground.

Q4: Can I take the bike on a ferry?

Absolutely. The Setouchi region is connected by a network of ferries. If you get tired, you can hop on a ferry from Ikuchijima or Omishima back to Onomichi. There is a small “bicycle fee” (usually ¥100–¥300) in addition to your passenger fare.

Q5: Is there a weight limit for the bikes?

Giant bikes generally have a weight limit of around 120kg-125kg (including the rider and any gear). If you have specific concerns, it is best to email the store directly when booking.

Conclusion: Final Planning Tips for Your 2026 Journey

Renting from the **Giant Store Onomichi** is an investment in your travel experience. While the prices are higher than the public rental options, the decrease in physical fatigue and the increase in reliability allow you to focus on what matters: the salty sea breeze, the citrus groves of Ikuchijima, and the architectural marvel of the Tatara Bridge.

Trip Planning Checklist:

1. **Book your bike 60 days out:** Especially if you want an E-bike or a specific carbon model.

2. **Stay at Onomichi U2:** It simplifies your morning logistics and is one of the most unique hotels in Japan.

3. **Check the Ferry Schedules:** Ferries can be a lifesaver if the weather turns or if you want to skip a particularly long bridge section.

4. **Carry Cash:** While Giant Store accepts credit cards, many small cafes and fruit stands on the islands are cash-only.

5. **Start Early:** Aim to pick up your bike right when the store opens (usually 9:00 AM) to maximize your daylight hours on the islands.

Cycling the Shimanami Kaido is a transformative experience. By securing a high-quality rental and understanding the costs involved, you’re setting yourself up for a smooth, exhilarating ride through the heart of Japan’s island sea. Prepare your legs, pack your camera, and get ready to discover why this is the world’s most beautiful cycling route.
