Dhruv Vidyut offers a conversion kit to electrify any bicycle. The kit includes a hub motor wheel, a battery pack, a controller, and all necessary accessories for installation. Their website highlights its ease of installation, affordability compared to buying a new e-bike, and customizability with different motor power and battery capacity options. It's marketed as a sustainable and practical solution for urban commuting and leisure riding, transforming a regular bicycle into a versatile electric vehicle.
"Take the Pedals Off the Bike" describes a highly effective method for teaching children to ride bicycles. The post argues that training wheels create bad habits by preventing children from learning the crucial skill of balance. By removing the pedals and lowering the seat, the child can use their feet to propel and balance the bike, akin to a balance bike. This allows them to develop a feel for balancing at speed, steering, and leaning into turns, making the transition to pedaling much smoother and faster than with traditional training wheels or other methods. Once the child can comfortably glide and steer, the pedals are reattached, and they're typically ready to ride.
Hacker News users discuss the effectiveness of balance bikes and the "pedals off" method described in the article. Many commenters share personal anecdotes of success using this approach with their own children, emphasizing the quick and seemingly effortless transition to pedal bikes afterwards. Some offer slight variations, like lowering the seat further than usual or using strider bikes. A few express skepticism, questioning the universality of the method and suggesting that some children may still benefit from training wheels. One compelling comment chain discusses the importance of proper bike fit and the potential drawbacks of starting with a bike that's too large, even with the pedals removed. Another interesting thread explores the idea that this method allows children to develop a more intuitive understanding of balance and steering, fostering a natural riding style. Overall, the comments generally support the article's premise, with many praising the simplicity and effectiveness of the "pedals off" technique.

Hacker News users generally praised the simplicity and ingenuity of the electric bicycle conversion kit shown on the linked website. Several commenters appreciated the clear instructions and readily available parts, making it a seemingly accessible project for DIY enthusiasts. Some questioned the long-term durability, particularly regarding water resistance and the strength of the 3D-printed components. Others discussed potential improvements, like adding regenerative braking or using a different motor. A few pointed out the legality of such conversions, depending on local regulations regarding e-bikes. There was also discussion about the overall efficiency compared to purpose-built e-bikes and whether the added weight impacted the riding experience.
The Hacker News post "Turn any bicycle electric" with the link to dhruvvidyut.co.in sparked a discussion with a moderate number of comments, mainly focusing on the practicality, cost, and existing alternatives to the presented DIY e-bike conversion kit.
Several commenters questioned the overall cost-effectiveness of the project. They argued that while the author emphasizes affordability, the price of the components, especially the battery, could quickly add up, potentially exceeding the cost of pre-built e-bike conversion kits or even inexpensive complete e-bikes available on the market. Some users shared their experiences with similar projects, noting that unforeseen expenses and the time investment required for assembly often make buying a ready-made solution more appealing.
Another recurring theme in the comments was the practicality of the friction-drive system employed in the DIY kit. Commenters expressed concerns about the efficiency and durability of such a system, particularly in wet weather or on challenging terrain. They pointed out the potential for slippage and wear on both the drive wheel and the bicycle tire. Some suggested that a mid-drive or hub-drive motor would be a more robust and efficient solution, albeit more complex to implement.
A few comments also touched upon the legal aspects of e-bike conversions, particularly regarding motor power and speed limits. They advised readers to research local regulations before undertaking such projects to ensure compliance with the law.
Some commenters appreciated the ingenuity and DIY spirit of the project, acknowledging its potential value for those with specific needs or a desire to tinker. However, the prevailing sentiment seemed to be one of cautious skepticism, with many users recommending thorough research and careful consideration of the costs and limitations before embarking on a similar endeavor. There was also a discussion around the potential noise generated by the friction drive system, with users expressing concerns about the high-pitched whine that can be characteristic of such designs. Finally, a few commenters suggested alternative DIY approaches using salvaged parts from old e-scooters or other electric vehicles as a potentially more cost-effective route to e-bike conversion.
