Consider your usage and budget, bikes like the TVS Ronin and Royal Enfield Hunter 350 will be options we recommend you take a look at. Both are smooth and comfortable machines with neutral riders' triangles, which will be conducive to long stints in the saddle. 

You can even take a look at the Hero Xpulse 210 if you want a dual-purpose machine. It will be the most comfortable and capable of the three bikes we've suggested here. 

However, it is also the tallest, so if you are a shorter rider who isn't comfortable with tall bikes, then this may not be the best bet for you. 

Take a test ride of everything you shortlist before you make a decision.

Considering your usage and budget, you can look at bikes like the Royal Enfield Hunter / Bullet / Classic 350, Honda CB350 trio, TVS Ronin and the Hero Xpulse 210. All have spacious seats, comfortable suspension and have decent braking performance too. A test ride of all these machines with your wife sitting behind you will help you decide which is the right fit for you. 

Do bear in mind that making the switch from a scooter to a motorcycle will need good hand and foot coordination to operate the clutch and gear pedal.  We recommend you practice on a used bike first before taking the plunge. 

In the electric scooter market, we would recommend you take a look at the Ather Rizta 2.9 variants, Bajaj Chetak 3001 and the TVS iQube 2.2 / 3.1 for your usage. All three have large storage spaces under the seat, with at least 30 litres of space available, if not more.

The Ather is the only one that will give you a touchscreen colour TFT display on the higher Z variants if that is of interest to you. If not, the S variants have the same underpinnings with a few features less while also costing much less. 

The iQube and Chetak are proven products and have a straightforward scooter riding experience. They are appreciated by lakhs of people and are sure to resonate with you as well. 

A test ride and visit to your nearest dealer to enquire about service costs is for all three in order to make a more informed decision. 

If you want to stay in the same displacement range as your Unicorn, you can look at the Bajaj Pulsar N160 and the TVS Apache RTR 160 4V. Both have great suspension, peppy performance and will return similar fuel economy to your Unicorn. 

If you want to make a step up, then bikes like the Royal Enfield Hunter / Bullet / Classic 350, TVS Ronin, and Honda CB350 trio will make for good commuting partners. These are bikes with upright, neutral ergonomics, plush suspension setups and torquey, smooth engines. Expect lower fuel economy in comparison to your Unicorn, however, by virtue of its larger displacement.

Lastly, the Hero Xpulse 210 is a wonderful do-it-all machine which will have the best suspension comfort of all the bikes listed here.

A test ride of all of these bikes will help you determine which one is best for you.

Considering your requirements, bikes such as the TVS Ronin, Honda CB300F, CB350 trio, Royal Enfield 350s, and Hero Xpulse 210 will serve you well. All are reasonably powerful bikes that can handle the weight of two-up riding and keep your passenger comfortable. 

A test ride of all these machines with your preferred passenger will help you make an informed decision. 

You are correct to be concerned about Aprilia's aftersales service as it is generally on the more expensive side, and the experience can also be hit / miss. Sticking with offerings from other brands like TVS, Yamaha and Suzuki would be our recommendation for a hassle-free ownership experience. 

Among your shortlisted options, the Jupiter, Ray ZR and Access are typical family scooters which will be comfortable, fuel-efficient and reliable in the long run. Our pick would be the Jupiter because it is the most rounded product, although the Access comes very close and is also noticeably quicker. 

Between the two sporty scooters, the TVS Ntorq makes for a better all-rounder because even though it is sporty, it doesn't sacrifice practicality or comfort. 

Take a test ride of all options you consider before making your purchase. 

In the 150-160cc commuter bike space, you have a good variety of options from different brands to choose from. Among the straightforward, simple commuter options, bikes like the Honda Unicorn / SP160 and Yamaha FZ models will be a good fit with their excellent fuel economy as well as comfortable ride and seating position. 

If you want something a little sportier, you could even consider the Bajaj Pulsar N160, which will also give you some features like a USD fork, which isn't found in most other bikes in the class. The TVS Apache RTR 160 4V is also a great option, but it can feel a little cramped, especially in the leg region. So we would recommend a test ride for all of these bikes before you decide. 

Since you have a longer commute, with its longer suspension and bigger wheels, a motorcycle will be more comfortable than a scooter, so we recommend going with a bike only.
