Everyone - I have been getting a LOT of requests lately for step-through frames. Literally 30-40% right now. When we started, we were doing may be 5% step throughs.
Are there any pointers / data for demand for step-through versus regular frame ?
Any pointers will be appreciated.
Hmm.. true.
1. Battery placement behind the seat tube is an option but it takes away the peppiness feel of the bike.
2. Battery placement on the rear rack is not ideal if its the only battery on the bike.
3. Having a better integrated battery upfront appears to be the best option.
4. In terms of integrted batteries, I saw the new Sondors design through.. it is 1100wh but ... umm... isnt it too bulky ?
1. Increases the chainstay length so makes it feel sluggish.1. Help us understand why this could be true.
2. Not ideal from a center of gravity (top heaviness) perspective either
3. But on hanging on handlebars (same rationale as #2 above)
4. idk, haven't seen it.
Make it a Transformer.
The removable cross bar can be an extra battery that transforms it from a step through to a diamond.

My take on this........whenever a review of a step thru was posted on this sight, there seemed to me an over hyped attention to frame flex. This probably turned a lot of people off right from the get go. I was one of those people. Now when a step thru is mentioned, it’s kind of just glossed over likes it no big thing. Better materials, new designs, are probably helping the step thru cause.
In the end the step thru design has caught on and become a legitimate frame style that is no longer questioned. The frame flex stigma, or girl bike phenomenon has been put to rest by the abundance of satisfied ownersThe first time I saw a step thru in person I immediately thought frame flex. However I was assured flex was not an issue. I agree assembly techniques and materials have improved. I also think the Step Thru rider is an older rider that has issue getting on their bike due to age , injury or both. The Step Thru rider is more likely to have a softer gentler approach to riding. Step Thru riders are less likely to ride on rugged challenging terrain that may compromise the integrity of the step thru frame.

I’m happy I don’t know any better!Or an abundance of owners who don't know any better... frame flex is a real issue with heavy EBikes.
Step-through frame - Wikipedia
en.wikipedia.org
A step-through frame (also known as open frame or low-step frame) is a type of bicycle frame, often used for utility bicycles, with a low or absent top tube or cross-bar. Traditionally, bicycles with a step-through frame were known as "Ladies'", "Women's", or "Girls'", mainly for their advantage to riders wearing skirts or dresses. Bicycles with a high top tube (cross-bar), known as a diamond frame, were known as "Men's", "Gents'", or "Boys'". As a result of changing clothing styles since the late 20th century, descriptions that describe the frame style, rather than the presumed gender of the rider, are becoming increasingly common.
Advantages
- less risk of stretching or ripping clothes when mounting the saddle
- the rider can wear a skirt (also requires a skirt guard and possibly a chain guard)
- very quick to mount and dismount, so is suitable for delivery bicycles, or any journey with many stops
- suitable for the elderly and others with restricted agility
Disadvantages
- Heavier Compared to a traditional diamond frame consisting of two near-triangles, open or step-through frame designs must be designed with thicker gauge tubing, the use of additional gusseting members, and/or monocoque frame construction. These structural elements may add weight or cost over a traditional diamond design.
- Inattention to structural design can lead to excessive flexing, resulting in lower pedaling efficiency and reduced frame life.
- Fewer places to mount accessories, e.g. an air pump or water-bottle.
- More difficult to carry around off the ground due to the sloping tube near the bicycle's center of gravity, e.g. carrying it up stairs, or lifting to hang it for maintenance.
