To determine the probability that the next two bicycles chosen are both silver, follow these steps:

1. **Total Bicycles Available:**
   - **Black Bicycles:** 4
   - **Silver Bicycles:** 6
   - **Total Bicycles:** 4 + 6 = 10

2. **Probability of Choosing the First Silver Bicycle:**
   $$
   P(\text{First Silver}) = \frac{\text{Number of Silver Bicycles}}{\text{Total Bicycles}} = \frac{6}{10} = \frac{3}{5}
   $$

3. **Probability of Choosing the Second Silver Bicycle (Without Replacement):**
   - After choosing one silver bicycle, there are now 5 silver bicycles left and a total of 9 bicycles.
   $$
   P(\text{Second Silver} \mid \text{First Silver}) = \frac{5}{9}
   $$

4. **Combined Probability:**
   $$
   P(\text{Both Silver}) = P(\text{First Silver}) \times P(\text{Second Silver} \mid \text{First Silver}) = \frac{3}{5} \times \frac{5}{9} = \frac{15}{45} = \frac{1}{3}
   $$

**Final Answer:** $$\boxed{\dfrac{1}{3}}$$
The probability that the next two bicycles chosen are both silver is $$\frac{1}{3}$$.
