At OHM we know the importance of providing a range frame sizes to accommodate every rider.  We go above and beyond most manufacturers offering 4 sizes in all our bike models, including an extra small 15" frame, and an Extra Large 22" frame. This attention to sizing ensures that riders of all heights can find an ergonomic, safe ride.

At OHM we've put careful consideration into creating the most ergonomic riding positions. These postures provide a low impact, comfortable ride.

My friend recently purchased 3 e-bikes from you and is very happy.
I am a client of his and am looking for an e-bike for my wife.
She will be 66 this year, is in great shape and stands around 5’2-5’3 but is afraid to fall.
What do you suggest please?
For road riding and taking along in our Jeep 4-door on excursions.
