To find the number of total bike rides, we must first determine how many times John rode his bike. We do this by performing 17*2= <<17*2=34>>34 times for John
Since John's mother rode 10 times more than John did, we find her total by performing 34+10=<<34+10=44>>44 times
For all three people put together then, we perform 44+34+17=<<44+34+17=95>>95 times in total
