こんばんは。ご質問ありがとうございます。
「電動アシスト自転車」とも言いますね。一例をご紹介します。
《語句》
electric
【形】電気で動く、電動の、電化された
bicycle
【名】自転車
bike
【名-1】自転車◆【語源】bicycleの省略形
【名-2】オートバイ、バイク
《解説》
☆ electric bicycle
〈electric+bicycle〉=〈電気で動く+自転車〉ということで、誤解の少ない言い方だと思います。
☆ electric bike
bike は bicycle が省略されたものです。日本語では「バイク」というと「オートバイ」を指すことが多いですよね。英語の bike にも「オートバイ」という意味がありますが、「自転車」という意味で使われることの方が多いです。
「オートバイ」は motorcycle や motorbike と言います。
☆ e-bike
接頭辞 e- は、ここでは electric の意味で使われています。

It's a bicycle that is not powered manually, but electrically. There are many electric bikes on the market now, especially for elderly people. A traditional bicycle has petals and the pedals are pushed manually or by one's feet. An electric bike has a power switch and a little motor that makes the wheels turn rather than the pedals. Some bicycles nowadays have both options, which can be comfortable for people. The pedals are there if you want to pedal the bike, but you can switch ot electric mode whenever you like, and the pedals don't move on electric mode.
We commonly refer to this kind of bike as an 'electric' bike - one that requires very little effort to make it run and can go easily uphill.
'Automatic' also refers to a bike that runs on electricity as it has automated movement and is not solely dependent on pushing!
Electric bikes usually come with a heavy battery installed - this is usually what adds to the weight of an electric bike; therefore, it can be called 'battery-operated'
An 'electric bicycle', e-bike, or power-bike, is a bicycle that is powered by an integrated electric motor. This type of bicycle is different from the age-old motor bike which uses petrol for propulsion. Electric bicycles need batteries, just like electric cars do. However, just like petrol runs out, batteries do lose power after some time and require re-charging whenever they do so.
So, you may say:
My uncle has just bought a brand new electric bicycle.
or
I will go by my e-bike today and beat the traffic.
or
I need to recharge my power-bike's batteries because they are completely flat.
electric bicycle'(電動自転車)、'e-bike'(同)または'power-bike'(同)は、内蔵された電動モーターによって動く自転車を言います。
このタイプの自転車は、ガソリンで走るオートバイ(motorbike)とは違います。'electric bicycle'は電気自動車と同様、電池で走ります。ただ、ガソリンと同じで電池も走っているうちになくなりますから、充電が必要になります。
ですので以下のように表現することができます。
My uncle has just bought a brand new electric bicycle.
私の叔父が新品の電動自転車を買いました。
I will go by my e-bike today and beat the traffic.
今日は電動自転車で行って、渋滞を免れるよ。
I need to recharge my power-bike's batteries because they are completely flat.
電動自転車の電池が切れたので、充電しないといけない。

There are two types of electric bikes, those which are traditional bicycles with a small motor and those which look more like a real scooter but are electric. In common colloquial English we use the term e-bike.
For example, I am going to rent an e-bike when I go to Vietnam.
Another sentence is - She is riding her e-bike to university.
"electric bike"(電気自転車)には二つのタイプがあります。
従来の自転車に小さなモーターを付けたものと、本物のスクーターのような電気の自転車です。
日常会話では一般的に"e-bike"(電気自転車)と呼ばれます。
【例文】
