自転車に乗れば、全力で走る時のスピードを簡単にだせるって英語でなんて言うの？

"自転車に乗れば、全力で走る時のスピードを簡単にだせる" - If you ride a bike, you can go as fast as you do when you run full speed. (直訳に近い) You can go as fast on a(the) bicycle easily as running with all your might. -> You can easily go as fast on a bicycle as fast as you run with all your might. その逆も：As fast as you run with all your might, you can easily go as fast on a bicycle. 自転車に乗って普通に走るスピードと、 自分の足で全力で走るスピードが一緒。 - The speed at which I normally ride a bike is the same speed as when I run as fast as I can.

ご質問ありがとうございます。 おっしゃったように、「You can go as fast on a(the) bicycle easily as running with all your might.」はほとんどいいです。 「You can easily go as fast on a bicycle as you can when running with all your might.」になります。 副詞の「easily」は「can」の後にきます。後は「you can when」があればもっと自然になると思います。「when」は「とき」と言う意味があります。 ご参考になれば幸いです。
