Day 1: Northwest on bike to Dien Bien Phu: Sapa - Heavens Gate - Binh Lu - Tam Duong 
You will start out from Sapa by cycling up the Vietnam's highest pass to "Heavens Gate". A break at the top of the pass will give you the opportunity to enjoy the picturesque view of the Sapa valley and the long snake-shaped road, which you will pass by later. You will then continue the cycle through the fantastic mountainous landscape to Binh Lu, home to a number of ethnic villages such as the Black Dao, The Giay... You will then probably need the help of the supply jeep to go up another high pass, before enjoying the easy ride downhill all the way left to Tam Duong, where you stay overnight in a small hotel.
Day 2: Northwest on bike to Dien Bien Phu: Tam Duong - Phong Tho - Paso
If today falls on Thursday or Sunday, you will be able to visit the Tam Duong market, which always delivers a very photogenic display of White Hmong, Flower Hmong, Nhang and Pu Na ethnic costumes.
You will start out from Tam Duong by taking the jeep to the pass between Tam Duong and Phong Tho. From there you have a 15 kilometers downhill ride on a dirt road before turning right towards the market town of Phong Tho, situated on a picturesque tributary of the Na River. A small road then leads you through the unexplored area of a number of ethnic villages and acres of lush riverside banana plantation to the small town of Paso.
Day 3: Northwest on bike to Dien Bien Phu: Paso - Sin Ho - Lai Chau 
The road today weaves its way through the picturesque Na river valley, past many small villages of Red and White Hmong, Kho Mu and White Thai ethnic minorities. The sound of the river running below follows you all along the ride until you reach to Lai Chau early afternoon. Then you will have the opportunity of having a walk around in the small town, soft trekking in the mountains, floating downstream the river...or just taking a shower and relax over a cup of coffee or a beer.
Day 4: Northwest on bike to Dien Bien Phu: Lai Chau - Dien Bien Phu
Today is the easiest day on the trip. You will start out by jeep for the first 30 km before cycling downhill to Muong Lay village. The road from Muong Lay to Dien Bien Phu is sealed, making your ride more enjoyable. Again today you will pass more ethnic villages of White Thai, Red and White Hmong and Kho Mu minorities.
In the afternoon you will reach Dien Bien Phu and 4 amazing adventure days on the bikes are over.
