You may want to wait with a lightweight bike
I read about an Israeli startup that manages to reduce the weight of the electric motor by 70 percent and increase the range of the battery twice
Interestingly, they have an agreement with the Bush company that plans to incorporate this technology into bicycles.
The following is a translation of the article from Hebrew to English:
IRP Systems from Ness Ziona announced today (Tuesday) that it has signed an agreement with the German company Bosch for the mass production of motor controllers that it has developed for electric vehicles. Alongside the products it develops and manufactures, Bush also offers manufacturing services for companies in the automotive industry. The collaboration with Bush will focus on the production of controllers for personal electric vehicles such as scooters, bicycles and small cars, which is the segment where IRP has the largest foothold today. The company's solutions have already been implemented in a number of commercial models and to meet the increase in demand it is now expanding its production capabilities through the agreement with Bosch.
Last year, she participated in the Renault-Nissan innovation lab in Tel Aviv. During this collaboration, its technology was tested in Renault's light electric vehicle. As part of a joint Proof of Concepts experiment, four electric motors and IRP control system were installed in the Twizy lightweight electric vehicle. The company reported that the size of the new engines is only about a third of the size of the original engines, and that they have achieved a doubling of the travel range between battery charges, and higher acceleration speed thanks to stronger torque of the engines.
The Bosch company announced that the test and automation - already in the planning stages. The knowledge will be implemented through the Bosch Electronic Manufacturing Services (EMS) unit located in Mondville, France, in collaboration with the local team of Bosch Technologies Israel.
